libipa_hbac: Move the library to src/lib/ipa_hbac Moving the library to the lib directory will force maintainers to think twice about changes, because it would be obvious this is a library. Also don't use includes from sssd source tree paths, but add the util path to Makefile's CFLAGS so that other projects can copy the hbac_evaluator.c file verbatim.
