Enable profile guided compilation on the framework side

The background compilation service will trigger a profile based
compilation instead of a full one. If no profile information is
available the compilation is skipped (see installd).

Note that the end decision whether or not to compile a package is taken
by dext2oat. We can't make the decision here because this service runs
under system server which cannot read app's profile data.
