Current usage of Werror=switch-enum by default for libvirt builds out
of the git tree causes issues when new items are added to libxl public
API enums if those are used in a switch statement in libvirt code.
This leads to libvirt build failures for seemingly unrelated libxl
changes.
In order to prevent those errors from blocking the push gate, disable
Werror for libvirt builds when not in a libvirt specific flight.
The errors will be reported on the libvirt flight, and block the
pushes there. So the author of the changes in libxl is still expected
to send a fix to libvirt code. This is no ideal, but the other option
is to just disable Werror for all libvirt builds and let libvirt
developers fix the breakage when they notice it.
runvar differences for a xen-unstable flight are:

I'm unsure whether we want o disable Werror even for libvirt flights,
but this seems more conservative.
This does at least unblock the libvirt builds for both the
xen-unstable and the libvirt flights.
