Fix permissions for zip files

Now [new_]http_archive can be used for executables as well as "default
permission" (644) files.

This also gets rid of the Apache Commons Compress dependency entirely, which is
nice. Fixing this also exposed some bugs in how archives were being decompressed
(the same archive was being decompressed multiple times), which I also fixed by
making the decompressors SkyFunctions.

Fixes #238.
