systemctl,verbs: Introduce SYSTEMD_OFFLINE environment variable

A lot of code references the `running_in_chroot()` function; while
I didn't dig I'm pretty certain this arose to deal with situations
like RPM package builds in `mock` - there we don't want the `%post`s
to `systemctl start` for example.

And actually this exact same use case arises for
[rpm-ostree](https://github.com/projectatomic/rpm-ostree/)
where we implement offline upgrades by default; the `%post`s are
always run in a new chroot using [bwrap](https://github.com/projectatomic/bubblewrap).

And here's the problem: bwrap creates proper mount roots, so it
passes `running_in_chroot()`, and then if a script tries to do
`systemctl start` we get:
`System has not been booted with systemd as init system (PID 1)`
but that's an *error*, unlike the `running_in_chroot()` case where we ignore.

Further complicating things is there are real world RPM packages
like `glusterfs` which end up invoking `systemctl start`.

A while ago, the `SYSTEMD_IGNORE_CHROOT` environment variable was
added for the inverse case of running in a chroot, but still wanting
to use systemd as PID 1 (presumably some broken initramfs setups?).

Let's introduce a `SYSTEMD_OFFLINE` environment variable for cases like
mock/rpm-ostree so we can force on the "ignore everything except preset" logic.
This way we'll still not start services even if mock switches to use nspawn or
bwrap or something else that isn't a chroot.

We also cleanly supercede the `SYSTEMD_IGNORE_CHROOT=1` which is now spelled
`SYSTEMD_OFFLINE=0`.  (Suggested by @poettering)

Also I made things slightly nicer here and we now print the ignored operation.

3. Normalize parameters to the call: separate out the path parameter in
   two: an input path and an output path. That way the memory management
   is clear: we will access the input parameter only for reading, and
   only write out the output parameter, using malloc() memory.
   Before the calling convention were quire surprising for internal API
   code, as the path parameter had to be malloc() memory and might and
   might not have changed.
4. Rename bootctl's find_esp_warn() to acquire_esp(), and make it a
   simple wrapper around find_esp_warn(), that basically just adds the
   friendly logging for the ENOKEY case. This rework removes double
   logging in a number of error cases, as we no longer log here in
   anything but ENOKEY, and leave that entirely to find_esp_warn().
5. find_esp_and_warn() now takes a bool flag parameter
   "unprivileged_mode", which disables logging in the EACCES case, and
   skips privileged validation of the path. This makes the function less
   magic, and doesn't hide this internal silencing automatism from the
   caller anymore.

With all that in place "bootctl list" and "bootctl status" work properly
(or as good as they can) when I invoke the tools whithout privileges on
my system where /boot is not world-readable

tree-wide: drop a few == NULL and != NULL comparison

Our CODING_STYLE suggests not comparing with NULL, but relying on C's
downgrade-to-bool feature for that. Fix up some code to match these
guidelines. (This is not comprehensive, the coccinelle output for this
is unfortunately kinda borked)
