logind: use pid_is_valid() where appropriate

Browse Source 
These two sites _do_ match the definition of pid_is_valid(); they don't
provide any special handling for the invalid PID value 0.  (They're used
by dbus methods, so the PID value 0 is handled with reference to the dbus
client creds, outside of these functions).
