pwhash - added -x option

I have the need to check against hashes generated by pwhash (I have a CGI
script doing logins).  I'd like an option in pwhash to explicitly specify
the setting for crypt() (rather than create a whole separate binary).  The
-s option almost does this except that it verifies that there is no $ in
the optarg (to ensure DES), so the changes to the source are minimal (5
lines).  I added a -x, the option argument explicitly specifies the crypt()
setting.

Anyway, just thought someone else might be interested.

P.S.  I'm not sure how to submit patches, but I ran `cvs diff` in
/usr/src/usr.bin/pwhash and this is the output
