[libvirt] Bug 736983 SSH GSSAPI login broken

[Matthias Witte]

Hi,

after I upgraded from libvirt-0.9.0 I noticed that GSSAPIAuthentication for
openssh was no longer working, I always ended up with the password prompt.

stracing and debug logging on the server revealed that gssapi was never
tried.

Adding KRB5CCNAME to the ssh command's environment solved the problem.

I would like to propose the following patch:
