uriparser: 0.8.2 -> 0.8.4 + fixed build

[c0bw3b]

Motivation for this change

Minor version bump + removed the creation of the HTML API documentation because :

1. it is available online on the website of the project
2. it requires doxygen, graphviz and qhelpgenerator which is part of the whole Qt framework...

This should be pushed to release-17.03 as part of #23253

Things done

• Tested using sandboxing
  (nix.useSandbox on NixOS,
  or option build-use-sandbox in nix.conf
  on non-NixOS)
• Built on platform(s)
  • NixOS
  • macOS
  • Linux
• Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Fits CONTRIBUTING.md.

The commit message needs an explanation why removing the docs is a good thing. (It generally isn't :-) )

@bjornfor Fair point.

I've reworked this and figured out what was blocking the build from the doc Makefile.
