Instead of relying on the regular iteration through the system
services inside dumpstate, dumpstate now uses a dedicated incident CLI
to capture incident report. This patch makes required SELinux changes
to make it happen.
Bug: 137493082
Test: Manually takes a bugreport from command line, power button, and
BetterBug. Verifies /proto/incident_report.proto exists in the
zip file, and no unintended avc denial.
