memory: Unify D-Bus PID type to be always int32
This commit changes following two D-Bus signal signatures to expect
PID argument as int32 type, not as uint32:
- "SetPerceptible" (u) -> (i)
- "SetPlatformSwap" (u) -> (i)
The reason for the change is following:
- Different signal handlers in memory module use different type
for PID argument (eg. "SetMemLimit" uses (i), "SetPerceptible"
and "SetPlatformSwap" use (u))
- PID is already of int32 type in the most of resourced D-Bus
functions
- Listed functions already use int32 in selected Tizen Product
forks (Mobile)
Note: The type is not compatible with D-Bus' spec GetUnixProcessID
(which expects uint32). Int32 PID is Tizen's system's specific.

Disable "reboot on VIP death" behavior on poweroff
This is done because it is normal for VIPs to die throughout a poweroff,
yet having the poweroff replaced by a reboot is undesirable.
Beware: there is a fallback that mounts (binds) `/bin/true`
as the usual release agent, `/usr/bin/vip-release-agent`,
which might cause surprises if the system somehow survives
the shutdown (e.g. because it is disabled for debugging).

Don't listen to DeviceD power off signal
DeviceD currently sends the ChangeState signal on the PowerOff interface,
which causes resourced's main loop to quit, before the PrePowerOff method
is called (which then is not handled). With PrePowerOff uncalled, the VIP
cgroup is left mounted, which causes the platform to reboot on the death
of any VIP process. This makes it impossible to do a regular poweroff as
VIPs die throughout which replaces the poweroff with a reboot.
Removing the signal handler is safe as the signal is somewhat redundant.
Quitting the main loop happens eventually regardless since at some point
DeviceD sends SIGTERM (which also quits the main loop).
