    Ensure relocatable packages always get install-prefix(es) set (RhBug:979443)
    
    - Scriptlets from relocatable packages should always run with
      $RPM_INSTALL_PREFIX* defined, whether actually being relocated or not.
    - Fixes regression introduced by the optimization in commit
      5d3018c4ed476b1b7ac18e2573af517f872cb303. We always need to call
      addPrefixes() but return early from rpmRelocateFileList() when
      no relocations are taking place, fixing the performance regression
      introduced all the way back in cb8241dda783f7e8c143b08fecf57fe89a39c3a6
      which is what 5d3018c4ed476b1b7ac18e2573af517f872cb303 was trying
      to fix. Pooh :)
