Tobiko stage was failing on Downstream OSP13 jobs because it tried to
install python3-devel from rhelosp-rhel-7.9-server-opt repository, which had
some problems with dependencies (specifically with package python3-libs)
With this patch, any other repo matching rhelosp-rhel-*-server-opt*
is enabled and python3-devel can be installed successfully
