ipatests: rpcclient now uses --use-kerberos=desired
The integration tests are using rpcclient delivered
by samba package. With samba 4.15, the options have
been renamed and "--use-kerberos=desired" must be
used instead of "-k".
(see
https://download.samba.org/pub/samba/rc/samba-4.15.0rc4.WHATSNEW.txt)
Adapt the test to be compatible with both old and new versions.
