Make SELinux initialization failure fatal

https://bugzilla.redhat.com/show_bug.cgi?id=572769

Previously we'd just continue if AVC initialization failed, but
that didn't really work because then we'd later crash in
avc_has_perm.

Simply treat initialization failures as fatal, and hopefully we
can get data from the system log.
