Fix selftests on EL7 and enable checks on package build

1. Added explicit build dependencies upon kmod to prevent test_lv_utils check
   failures.
2. Modified test_build_docs to explicitly ignore bogus warnings due to a bug
   in older versions of python-sphinx package causing checks to fail.
3. Enabled EL7 checks during package build.
