- HACK: do not build the -testsuite flavor in distro projects (i.e
in repositories called 'standard'). Allows to get fixes included
in the distro while the test suite actually still fails
(boo#1205140).

This does obviously not fix the test suite - but at least it allows us to
get fixes from the devel prj into Factory; maybe someday, somebody cares
for the test suite again
