[PATCH] Makefile.common: correct URL to Koji setup page in the wiki

[Till Maas]

Aloas,

the attached patch changes the URL in Makefile.common for Koji client setup 
from
http://fedoraproject.org/wiki/BuildSystemClientSetup
to
http://fedoraproject.org/wiki/PackageMaintainers/BuildSystemClientSetup

The first URL is a redirection to the second one.

If this is not the correct place to post a patch, please give me a pointer. I 
will write then a patch to Makefile.common to include a comment with the 
correct place/URL/procedure to submit patches.

Regards,
Till
