Some policy modules define file contexts in /bin, /sbin and /lib without
defining similar file contexts in the same directory under /usr.
Add these missing file contexts when there are outside ifdef blocks.
Remove file context aliases and update file context paths to use the /run filesystem path.
Add backward compatibility file context alias for /var/run using applications like https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=783321
Lock files are still seated at /var/lock
Since sudo 1.7.4, the timestamp directory has moved from /var/run/sudo to
/var/db/sudo, lib or adm (in that order). See also the sudo changeset
http://www.sudo.ws/repos/sudo/rev/8c9440423d98
Keeping the "old" one (/var/run/sudo) for a while for those systems where
sudo has not been updated yet (change is since 1.7.4, Jul 14 2010).
