allow system_app domain to be profiled

An example app in this domain is com.android.settings.

This was an accidental omission from https://r.android.com/1966610.
Context and rationale remain the same as for that patch, please see the
bug.

Tested: both traced_perf and heapprofd successfully profiled the
settings app with the right additional profileability permissions on a
user build (beta candidate).
