[libvirt] [jenkins-ci PATCH] jobs: Unset $CC for Go and MinGW jobs

[Andrea Bolognani]

We want $CC to be set so that ccache is used by default, but
some jobs (Go and MinGW) don't like that very much.

Later on, we might consider building a link farm so that we
can use ccache without having to set $CC; for the time being,
work around the issue at the job level.
