Replace libsuspend with android.system.suspend@1.0

This change only replaces libsuspend's suspend loop with the one in
android.system.suspend@1.0.

Native wake lock behavior is unaffected as they are still handled via
/sys/power/wake_[un]lock.

Bug: 78888165
Test: device boots, suspends when left alone
