Update bug component from Android Systems to OTA client

It's been a while since the Android Systems bug component does not
access the creation of new bugs for triage, instead, new bugs must
be created in the subcomponents of the team.
This change updates the bug component originally associated to this
subsystem from the Android Systems' 30545 to OTA client's 1014951.
