AID_SHARED_GID is a GID shared by a specific app across all users on the same device. Bring the UserHandle and multiuser.c implementations into agreement, and copy/paste the unit tests that verify that both behave identically. This fixes a regression where multiuser_get_shared_gid() was applying per-user isolation when it shouldn't have.
