    post-transaction-actions: fix filename matching. BZ 1045494
    
    I believe the code now works as origanally intended. When installing
    packages, txmbr.po is AvailablePackage instance and .filelist access
    may trigger filelist metadata download.
    
    Since this runs after the transaction, we may look the package up
    in rpmdb instead.  On removals, thispo is RPMInstalledPackage already.
    Thanks to Robert Tomczyk <robert.x.tomczyk@gmail.com> for reporting
    and testing this.
