replace: Remove crypt() reimplementation
Use of Samba with plaintext authenticaiton is incredibly rare, even more
rare is plaintext authentication on systems without a crypt() call and
where DES based crypt() would be the right thing to do.
Remove this additional cryptographic code per our current efforts
to rely entirely on external libraries instead.
Similar to the arguments in this thread about zlib discussed on
samba-technical here:
