Support tar response files / file list and output path transform

[amyspark]

Hi!

Just going over features of tar we use at GStreamer, and I thought these would be useful:

• output path transformation (https://gitlab.freedesktop.org/gstreamer/cerbero/-/blob/main/cerbero/packages/disttarball.py#L194-196) (currently ouch outputs relative paths verbatim only)
• file lists, though I suppose response files would be way more useful, especially on Windows (https://gitlab.freedesktop.org/gstreamer/cerbero/-/blob/main/cerbero/packages/disttarball.py#L212-217)
