Description of problem:

mrepo fails to obtain the createrepo version number. This prevents the repomd format metadata from being generated.

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

mrepo-0.8.6-5.fc12.noarch

How reproducible:

Always

Steps to Reproduce:
1. Configure a repomd format repo
2. Run mrepo, e.g., with "mrepo -fg <repo>"
  
Actual results:

$ mrepo -c scratch/mrepo.conf -fg f12-i386

Expected results:

Success, creation of metadata

Additional info:

These lines in mrepo (/usr/bin/mrepo) attempt to get the createrepo version number from the "genpkgmetadata" class:

 813         ### Find the createrepo version we are using (due to groupfile usage changes)
 814         createrepo_version = None
 815         groupfilename = 'RPMS.%s/comps.xml' % self.name
 816         try:
 817             sys.path.append("/usr/share/createrepo")
 818             import genpkgmetadata
 819             createrepo_version = genpkgmetadata.__version__
 820             sys.path.remove("/usr/share/createrepo")
 821             del genpkgmetadata
 822         except:
 823             pass

whereas __version__ has been moved to the "createrepo" class in some revision of creatrepo. This patch makes it work:
