We suppress calls from radio processes (including the basic phone
process) to the media.metrics service. This had started happening
for a particular video telephony application that ran within phone
instead of as some separate app with its own user id.
We do this here to speed up when a radio process learns that it
can not log to media.metrics. The existing sepolicy restrictions
remain in place as a fallback. The use case that prompted this
was having issues with the 5-second timeout before we learned that
radio wasn't allowed access to the media.metrics process.

Changes for the new HAL structure have brought about a build time
circular dependency between libmedia and libmediadrm. This set of
changes the media metrics code into its own library and arranges
for the relevant consumers of the media metrics code to link
to this new library (where they had previously picked it up by
including libmedia).
