init: Take wakelock on zygote restart 

If the framework is restarting (and cannot yet aquire
wakelocks to block suspend). Take a kernel wakelock
to allow the system to make sufficient progress before
autosuspend can be triggered.

The wakelock is later disable when the framework has
and invokeds enableAutosuspend() on the suspend service.

Bug: 255898234
Test: adb shell "echo mem > /sys/power/state && killall system_server"
