DfsPackFile: Use getPackIndex while loading bitmaps

In regular packs, getPackIndex() just calls idx() to load the index if
necessary. In midx packs, we override getPackIndex() to offer an
implementation directly over the midx data. In midx packs, this call
tries to load the index from the INDEX extension in the pack
(which is not populated), which is wrong.

Inline idx() into getPackIndex() and use the public method
everywhere. The distinction is meaningless and gets on the way to
subclassing.
