Introduce the add_service() macro which wraps up add/find
permissions for the source domain with a neverallow preventing
others from adding it. Only a particular domain should
add a particular service.
Use the add_service() macro to automatically add a neverallow
that prevents other domains from adding the service.
mediadrmserver was adding services labeled mediaserver_service.
Drop the add permission as it should just need the find
permission.
Additionally, the macro adds the { add find } permission which
causes some existing neverallow's to assert. Adjust those
neverallow's so "self" can always find.
Test: compile and run on hikey and emulator. No new denials were
found, and all services, where applicable, seem to be running OK.

All SELinux domains are already granted the ability to read the
filenames in /proc, so it's unnecessary to add it to storaged.te.
$ grep "proc:dir r_dir_perms" public/domain.te
allow domain proc:dir r_dir_perms;
Remove redundant rule.
Test: policy compiles.
