Removed vlimit.3 and vtimes.3. Removed vlimit.c and vtimes.c from
the "MISSING" list. These were old variants of get/setrlimit() and
getrusage(), respectively, and were never implemented in FreeBSD.
vlimit.3 referred to <sys/vlimit.h> which was removed recently.
vtimes.3 referred to <sys/vtimes.h> which never existed in FreeBSD.
