xserver_t needs to ender dirs labeled xdm_var_run_t

The LightDM application stores its xauth file in a subdirectory
(/var/run/lightdm/root) which is labeled as xdm_var_run_t. As a result,
X11 (xserver_t) needs search rights to this location.

With this setup, X is run as follows:
  /usr/bin/X :0 -auth /var/run/lightdm/root/:0

Changes since v1:
- Use read_files_pattern instead of separate allow rules

Enable rcs2log location for all distributions

Currently, the /usr/share/cvs/contrib/rcs2log is only labeled as bin_t
for redhat distributions. Moving this to the general one as it is also
in use on other distributions

Allow init to execute shutdown

In many inittabs, there's a line like
"ca:12345:ctrlaltdel:/sbin/shutdown -h now" which triggers a shutdown or
a reboot on Ctrl+Alt+Del.
Allow xdm_t to transition to shutdown_t domain

Several DMs offer the possibility to shutdown the system. I personally
don't think a bool is neccessary for this permission, but I wouldn't
oppose one either.
