Revert r310507 by putting pkg-plist back. The problem is that w/o pkg-plist
file installation of this ports hangs on "Generating temporary packing list"
stage. I discovered that while testing of libtorrent-rasterbar-16-python update
on a live system (while build is fine in tinderbox tests). I found exactly the
same report at  while googling of the problem.
Sorry about that.
