selinux.c: do not use deprecated typedef and skip context translation

Browse Source 
These retrieved contexts are just passed to libselinux functions and not
printed or otherwise made available to the outside, so a context
translation to human readable MCS/MLS labels is not needed.
(see man:setrans.conf(5))

The typedef security_context_t is deprecated, see
