Olivier Certner 892654fe9b setusercontext(): Apply personal settings only on matching effective UID 
Commit 35305a8dc1 (r211393) added a check on whether 'uid' was equal
to getuid() before calling setlogincontext().  Doing so still allows
a setuid program to apply resource limits and priorities specified in
a user-controlled configuration file ('~/.login_conf') where
a non-setuid program could not.  Plug the hole by checking instead that
the process' effective UID is the target one (which is likely what was
meant in the initial commit).
