build: add a tmpfiles.d config file for /run/gluster

New distrubutions have a /run directory on a volatile tmpfs filesystem.
This causes /run/gluster to be removed with each reboot. A tmpfiles.d
configuration is used to create the directory on boot.

EL5 and EL-6 do not use /run, current Fedora versions do. By checking
%{_tmpfilesdir} in the .spec, we can identify if the distribution uses
tmpfiles.d.
