gitian: create debug packages for linux/windows

The -debug tarballs/zips contain detached debugging symbols. To use them, place
in the same dir as the target binary, and invoke gdb as usual.

Also, because the debug symbols add a substantial space requirement, the build
dirs are now deleted when they're no longer needed.
