CI: Add tests for onf-make

Since this is a library of makefiles, standard code tests can't be
implemented. Instead, this change introduces modified versions of
build & test jobs for other repos, which are kicked off by pushes
to onf-make, and test those builds with the change to the onf-make
library.
