Permit mediaextractor its own file source for apk and ringtone files.

Previously we fall back to the mediaserver file source.
This does not affect behavior as the fallback works fine; however,
the log messages may cause confusion.

The new binder_call() lines had to be added
because this change removes mediacodec from
binderservicedomain (on full-treble), hence
domains that could previously reach mediacodec
with binder_call(domain, binderservicedomain)
now need explicit calls instead.

This unbreaks user builds broken by recently landed changes to secilc
which is now aggressively removing attributes which aren't used in
allow rules, even when they are used in other places, such as being
referenced from *_contexts files.

User builds are broken by vndservice_manager_type not being found when
checkfc is run for *vndservice_contexts targets.

service with hwservicemanager and which domains can obtain tokens for
this service from hwservicemanager.

hwservicemanager can check hwservice_contexts files
both from the framework and vendor partitions.

Initially, have a wildcard '*' in hwservice_contexts
that maps to a label that can be added/found from
domain. This needs to be removed when the proper policy
is in place.

Also, grant su/shell access to hwservicemanager list
operations, so tools like 'lshal' continue to work.
