Description of problem:
By default, dc_client attemtps to create /var/run/dc_client.pid as
nobody. This doesn't work as as /var/run is not writeable by any
others than root.

Version-Release number of selected component (if applicable):
distcache-1.4.5-1

How reproducible:
Always

Steps to Reproduce:
1. /sbin/service dc_client start
or
1. "/usr/bin/dc_client -pidfile /var/run/distcache/dc_client.pid
-listen UNIX:/var/cache/mod_ssl/distcache -sockowner apache -sockperms
0600 -user nobody -server IP:localhost:5555"
3. ps ax|grep dc_client
3.
  
Actual results:
Nothing there

Expected results:
Should work

Additional info:
I guess the easiest thing would be to create /var/run/distcache and
let nobody:nobody write to it. Alternatively the pid file creation
could be moved to an earlier point in the code but I'm not sure if
that is smart.
