Distribute p7zip and libz via our BB tarball bundling

This provides a number of benefits:

* Significantly reduces the amount of work in win-extras, which I've
always thought was an annoying wart in our build system.

* Provides a consistent 7z executable on all platforms, which can be
picked up by Pkg/BinaryProvider for consistent
unzipping/untarring/ungzipping on all platforms. Note that on Windows,
7z is a repackaged binary from sourceforge and is the "full" 7z, whereas
on all other platforms it is a p7zip build of the standalone 7za
executable with all relevant patches applied. There are some format
capability differences, but for the important things it should be fine.
