Subject: [PATCH] Only send started broadcast for main sysui process

Protected broadcasts can only be sent by system apps and since the sysui
started broadcast is protected, it should only be sent by the system
(user 0) process.

Bug: 266454339
Test: manual
Change-Id: I87fd07f927902a36dbe62eec954b9a716c416b5b
