nixos-manual: Further simplify stripAnyPrefixes
First of all this fixes an evaluation error I introduced in ae466ba, which wasn't triggered by any of my own tests against the change because there are usually no NixOS options that are declared outside of the <nixpkgs> tree. I renamed the attribute name from "fn" to "fileName" first and later to "fullPath" but forgot one still occuring "filename". Thanks to @vcunat for noticing this. Another thing that he pointed out was that the "stripPrefix" function can be factored away entirely, because it's very similar to "removePrefix" in <nixpkgs/lib>. Unfortunately we can't use "removePrefix" as is, because we need to account for the final shlash. So instead of removing it twice and/or retaining "stripPrefix", let's append a shlash on every "prefixesToStrip" and we can use "removePrefix" as is. Tested with: taalo-build nixos/release.nix -A tests.installer.simple.x86_64-linux And: w3m -dump "$( nix-build nixos/release.nix -A manual.x86_64-linux )/share/doc/nixos/options.html" Signed-off-by: aszlig <aszlig@redmoonstudios.org> Cc: @vcunat
