patch for kojid to prevent noarch build failures

[Jesse Keating]

Today a number of builds were failing on xenbuilder2/4.  They were perl
noarch builds.  The failure output was like:

+ '%{_fixperms}' /var/tmp/perl-Module-ExtractUse-0.22-1.fc8-root-/usr
/var/tmp/rpm-tmp.90217: line 32: fg: no job control

I investigated a failed buildroot and discovered that _fixperms was not
being evaluated and translated in the rpm script as it should have
been.  _fixperms is an arch specific macro, and that led me to do some
testing with how the mock rebuild is being called in noarch cases.

Turns out, this is something I already fixed in upstream koji.  Koji
was unnecessarily calling mock with --arch noarch in the noarch build
cases.  I hadn't realized this was going to cause builds to fail so I
hadn't done an upstream release with this fix yet.  However since this
is failing builds, I'm going to patch the builders manually.  Here is
the fix:

https://fedorahosted.org/koji/changeset/a023693e32d663ab7ad4f4fc85912c987...

I'm providing this here should something happen and the builders get
reverted before I do the next koji upstream release.
