[libvirt] Pass additional environmental variables

[Sean Noonan]

We're using sasl+gssapi+kerberos to do authentication for libvirt,
including from hypervisor to hypervisor.  However, the environmental
variable filtering implemented in libvirt prevents this from working, so
we're forced to run a locally patched version.

Thoughts on the following patch to pass the location of the local
credential cache as well?
