Get rid of the last vestiges of the old MOUNT_* constants in the

mount_* programs.  While we're at it, collapse the four now-identical
mount programs for devfs, fdesc, kernfs, and procfs into links to
a new mount_std(8) which can mount any really generic filesystem
such as these when called with the appropriate argv[0].

Also, convert the mount programs to use sysexits.h.
