systemd: split out systemd-binfmt as a separate package

If binfmt_misc was compiled as a module but isn't installed then systemd-binfmt
will put an automounter on /proc/sys/fs/binfmt_misc and when it attempts to
automount (e.g. when df is called) it can't find support for the filesystem, and
throws an error.

As binfmt_misc isn't commonly used, split this helper into it's own package, add
a dependency on kernel-module-binfmt-misc, and ensure the service gets started
when it's installed.
