Revert "device: take wakelock on zygote restart"

In Android 14 we observe:

init: Command 'write /sys/power/wake_unlock zygote_kwl' action=sys.boot_completed=1 (/vendor/etc/init/init.am62p.zygote_wakelock.rc:9)
took 1ms and failed: Unable to write to file '/sys/power/wake_unlock': Unable to write file contents: Invalid argument

Moreover, [1] has been merged.

This reverts commit 3d74cd7c.
