Close PR#17. This may be a contraversal fix in that now mount will

spit out two error lines for a bogus filesystem type, e.g:

root@time-> mount -t foo /dev/sd0a /mnt
mount: exec /sbin/mount_foo for /mnt: No such file or directory
mount: exec /usr/sbin/mount_foo for /mnt: No such file or directory

But I would submit that if you're even going to scan multiple directories
for a mount_foo (which I actually think is somewhat bogus - if it's not
in /sbin, you're probably in big trouble anyway), you should emit an error
for each one.  I got multiple complaints (in addition to the PR) that the
existing behavior was very confusing.
