policycoreutils: split packages and bump to 2.7

policycoreutils: split packages and bump to 2.7

Policycoreutils was broken up into several packages, as such several
changes needed to happen for this patch to work:

- Remove patches 3, 4, and 5 as they no longer apply.
- Refresh patches 1 and 2 to work with version 2.7
- Remove semodule_${deps,expand,link,package} and sestatus from the makedirs
  in the mk file.
- Remove restorecond from the make and config file. (Seperate package)
- Remove Audit2allow from the make and config file. (In a different package)
- Remove the package sepolgen
- Add the package selinux-python
- Add the package restorecond
- Add the package semodule-utils
- Add the relevant Config.in.legacy options into the menu.

Because these are utilities that work on top of python, the older versions of
these utilites still work, and as such this should be a single patch.
