Fix: libcrmcommon: Drop stonith-timeout from pcmk_stonith_param()
Pacemaker does not handle stonith-timeout (PCMK_STONITH_STONITH_TIMEOUT)
specially as a resource parameter, so pcmk_stonith_param() should not
return true for it. It is unclear to me from the commit history why we
returned true for it in the first place.
