cgit cannot serve patches with stable hashes, so store these patches
in-tree. cgit community discussion about this problem:
https://lists.zx2c4.com/pipermail/cgit/2017-February/003470.html
We pull the patches in-tree rather than strip cgit footers with fetchpatch
because per https://github.com/NixOS/nixpkgs/pull/61471#issuecomment-493218587
dependencies of fetchpatch cannot use fetchpatch.
Verification that the only difference between the live page, the
patch committed here, and the version cached under the old hash at
tarballs.nixos.org is the cgit version footer:
