Commit 794c8b0b3f fixed the race condition
when requesting data wipes via uncrypt. We have similar issue with
RecoverySystem.installPackage(). It first requests to set up the BCB,
then triggers a reboot. These two steps should finish atomically.
This CL switches to calling
RecoverySystemService.rebootRecoveryWithCommand(), which guards the two
steps with synchronized blocks.
Bug: 34239871
Test: Having two apps: one calls RecoverySystem.cancelScheduledUpdate()
continuously, and the other calls RecoverySystem.installPackage()
just once. The install request should not be cancelled by the
other.
