[PATCH] Rewrote parts of pkgorder script to improve it's speed. (#451083)

[Martin Gracik <mgracik redhat com>]

Function printMatchingPkgs() was making glob.glob calls everytime it was used.
Rewrote parts of the script to build the list of the packages just once,
and then use fnmatch() to print the matching packages.
Also some unnecessary import calls were removed.
