tests/vm_qrexec_gui: do not swallow stderr on failure

Browse Source 
QubesVM.run_for_stdio() by default captures stderr. In case of call fail
(non-zero return code), captured stderr is included in the exception
object, but isn't printed by default CalledProcessError message.
Make it visible by:
 - handling CalledProcessError and including in the test failure message
   (when exception is captured already)
 - not capturing stderr (if no exception handling is present in the
   test)
