Subject: [refpolicy] [PATCH 1/1] 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
