Make sure callingPackage belongs to callingUid when checking BG-FGS restrictions.

This is to stop spoofed packageName to pretend to be allowListed
packageName so it can bypass the BG-FGS restriction. This applies to
both BG-FGS while-in-use restriction and BG-FGS-start restriction
since these two restrictions are related.
