Switch to upstream refpolicy

[marshalljmiller]

Lots of work to get graphical logins working. Only tested with a non-root user with the staff_u user. This still has some problems including only being able to login once and not being able to reboot from X or gdm.

Tested with the following packages installed: selinux-policy selinux-policy-mcs selinux-policy-mcs-accountsd selinux-policy-mcs-aide selinux-policy-mcs-bind selinux-policy-mcs-colord selinux-policy-mcs-devicekit selinux-policy-mcs-geoclue selinux-policy-mcs-gnome selinux-policy-mcs-rngd selinux-policy-mcs-rtkit selinux-policy-mcs-ssh selinux-policy-mcs-sssd selinux-policy-mcs-telepathy selinux-policy-mcs-unprivuser selinux-policy-mcs-wm selinux-policy-mcs-xserver
