Add bunch of links to test-suite chroot to allow selinux to work

- With the new warning on failure to open selinux labels from
  commit 7a8b75d26605cf7a3fde9f624a80d6fb8390fcbd, the test-suite
  fails on large number of tests due to the extra output. This
  takes care of these false alarms on F16 at least.
- Recent selinux wants /etc/selinux and /sys (for /sys/fs/selinux),
  older ones would want /selinux. Add in /proc for good measure,
  selinux doesn't need it butit wont hurt either, other things will
  want it sooner or later.
