nixos/*: normalize link format

make (almost) all links appear on only a single line, with no
unnecessary whitespace, using double quotes for attributes. this lets us
automatically convert them to markdown easily.

the few remaining links are extremely long link in a gnome module, we'll
come back to those at a later date.
