Don't use find(1) before nfs filesystems have been mounted as

it lives in /usr/bin.  Instead, locate files manually.

Note, only *files* under /var/spool/lock are now deleted rather
than everything that's not a directory.  I think this is more
correct, but if anyone disagrees please feel free to change it.
