`SDL_gfx.pc` refers to `sdl.pc`. In addition to that some `SDL_gfx`
headers import `SDL.h` directly. I noticed it when attempted to build a
small SDL demo project which imports only `SDL_gfx`. It out to have
worked. Instead build fails as:
$ SDL1_CFLAGS=$(shell pkg-config SDL_gfx --cflags)
...
Package sdl was not found in the pkg-config search path.
Perhaps you should add the directory containing `sdl.pc'
to the PKG_CONFIG_PATH environment variable
This change is enough to make it work.

This updates the source urls of all top-level packages from http to
https where possible.
* buildtorrent: fix url and tab -> spaces
Semi-automatic update generated by https://github.com/ryantm/nix-update tools. These checks were done:
- built on NixOS
- Warning: no binary found that responded to help or version flags. (This warning appears even if the package isn't expected to have binaries.)
- found 2.0.26 with grep in /nix/store/cbvm4r21kf3acf43hff5sf6r1vbd6lpg-SDL_gfx-2.0.26
* pkgs: refactor needless quoting of homepage meta attribute
A lot of packages are needlessly quoting the homepage meta attribute
