selinux: always use *_raw API from libselinux
When mcstransd* is running non-raw functions will return translated SELinux context. Problem is that libselinux will cache this information and in the future it will return same context even though mcstransd maybe not running at that time. If you then check with such context against SELinux policy then selinux_check_access may fail depending on whether mcstransd is running or not. To workaround this problem/bug in libselinux, we should always get raw context instead. Most users will not notice because result of access check is logged only in debug mode. * SELinux context translation service, which will translates labels to human readable form
