Wire up remaining system calls: sched_setparam, sched_getparam, sched_setscheduler, sched_getscheduler, sched_get_priority_max, sched_get_priority_min, sched_rr_get_interval, sched_yield, cpuset, cpuset_setid, cpuset_getid, cpuset_getaffinity, cpuset_setaffinity, modfnext, modfind, kldload, kldunload, kldunloadf, kldfind, kldnext, kldstat, kldfirstmod, kldsym, posix_fallocate, posix_openpt, getrandom, kenv, cap_rights_limit, cap_ioctls_limit, cap_fcntls_limit, cap_enter, syscall, and __syscall. We also reshuffle a few system calls here to match the blitz branch which adds some churn, but is the least bad way to deal with the issues.
