test-login: always test sd_pid_get_owner_uid(), modernize

Browse Source 
A long time some function only worked when in a session, and the test
didn't execute them when sd_pid_get_session() failed. Let's always call
them to increase coverage.

While at it, let's test for ==0 not >=0 where we don't expect the function
to return anything except 0 or error.
