[PATCH] virnetsshsession: Adapt to changed libssh2 API

[Michal Privoznik]

In one of its commits [1] libssh2 changed the 'text' member of
LIBSSH2_USERAUTH_KBDINT_PROMPT struct from 'char' to 'unsigned
char'. But we g_strdup() the member in order to fill 'prompt'
member of virConnectCredential struct. Typecast the value to
avoid warnings. Also, drop @prompt variable, as it's needless.

Here's a somewhat green CI:

I mean, we still have failures on rawhide, but that's because numad was
temporarily removed from repos, but they are bringing it back. So ignore
that part. Apparently our CI images were not rebuilt this morning.
