[PATCH 2/2] meson: Check for sched_get_priority_min()

virProcessSetScheduler() uses not just sched_setscheduler() but also sched_get_priority_{min,max}(). Currently we assume that the former being available implies that the latter are as well, but that's not the case for at least GNU/Hurd. Make sure all functions are actually available before attempting to use them.
