Drop incorrect change for hostname location. The hostname binary moved place in Fedora 17 as part of the usr move feature and /bin is symlinked to /usr/bin. Just specify the actualy proper package name instead of a specific binary path.

Cleanup sources file just to include the current source. Please use "fedpkg new-sources"
command to properly upload sources. Otherwise each time a build is done, or even
"fedpra srpm" or "fedpkg prep" it downloads all the sources specified in the file
