[yocto] [meta-selinux] Updated meta-selinux -- master-next

[Mark Hatle]

I have updated meta-selinux, and placed the update into the 'master-next' branch.

This was locally tested with Poky as of commit 
853bc53cd58a621918f0e5ce662dba263d1befb4.

Note, when building the core-image-selinux, the internal refpolicies cause a lot 
of failures.  I'm not an expert on how this should be configured, so I'm looking 
for help/patches from others.

If you know of any other additional patches that should be applied, or are able 
to help with the refpolicies, please let me know!

Thanks!
