SELinux fixes and updates to 2012-09-24

I know nothing about SElinux, so I'll keep the updates here until someone reviews and/or tests (everything build on my machine). We probably want to be careful about these packages.

I presume it's best to keep the SELinux packages in sync, so that's what the <code>libsepol.se_release</code> is supposed to do in future (and simplify updating).
