define SELINUX_TRANS_DIR in selinux.h

I wanted to separate this directory out in order for a new patch to mcstransd to watch
this directory for newly created files, which it could then translate.

The idea is libvirt would write to /var/run/setrans/c0:c1,c2 with the contents of vm1, then
setrans could translate the processes to show system_u:system_r:svirt_t:vm1
