r12411: Add 'net samdump keytab <keytab>'.

This extracts a remote windows domain into a keytab, suitable for use
in ethereal for kerberos decryption.

For the moment, like net samdump and net samsync, the 'password
server' smb.conf option must be set to the binding string for the
server. eg:

password server = ncacn_np:mypdc
