privapp-permissions: add all privileged permissions for GmsCore and FakeStore

The previous whitelist only granted FAKE_PACKAGE_SIGNATURE. With
ro.control_privapp_permissions=enforce, PKMS throws a fatal exception
for each missing privileged permission, killing system_server before
ActivityManagerService can register — causing the bootloop.

Added all android.permission.* entries with protectionLevel including
"privileged" that GmsCore and FakeStore declare in their manifests.
