[Buildroot] [git commit] pkg-download: update the github helper

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=507d6a637ba51e9799acd4c8a0b614fc9842b4e2
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Once again, github updates the source download url.
Even if only the zip archive link is advertised on the repositories'
page, the *.tar.gz is still available.

It is worthy to note that the tarball's content differs depending if
it has been fetched from the former and the new url (the root directory
name changes).
