Mark Salyzyn d33a9a194b logd: restrict access to /dev/event-log-tags
Create an event_log_tags_file label and use it for
/dev/event-log-tags.  Only trusted system log readers are allowed
direct read access to this file, no write access.  Untrusted domain
requests lack direct access, and are thus checked for credentials via
the "plan b" long path socket to the event log tag service.

Test: gTest logd-unit-tests, liblog-unit-tests and logcat-unit-tests
