[libvirt] [PATCH] maint: prohibit translations in testsuite

[Eric Blake]

Nothing in the testsuite or examples directory should be translated,
as it is not part of the normally installed binary.  We already
meet this rule, but enforcing it will make it easier to remember.

Suggested by Daniel P. Berrange.

* cfg.mk (sc_prohibit_useless_translation): Enhance rule.
