Address bug report denials.
Triggering a bug report via
Settings > Developer Options > Take bug report
generates a number of denials.
Two bugs here:
1) According to the "allowed" list in
frameworks/native/cmds/servicemanager/service_manager.c ,
media apps, nfc, radio, and apps with system/root UIDs can register
as a binder service. However, they were not placed into the
binder_service domain. Fix them.
2) The bugreport mechanism queries all the services and java
programs and asks them to write to a shell owned file. Grant the
corresponding SELinux capability.
Addresses the following denials:
