[libvirt] [PATCH] build: force -Werror for distcheck target

[Daniel P. Berrangé]

The 'make distcheck' target validates that a tarball builds and
is ready for release. We expect that libvirt builds cleanly on
all supported platforms, so we should be enabling -Werror when
running distcheck.

This ensures that our CI systems in turn also use -Werror.
