When using tools like nixpkgs.lib.attrsets.mapAttrsToList and trying to build derivations where nix store file names are to be created, set attributes like ".stack/config.yml" are invalid, so stringToValidNixPath cleans them up to allow them to be created in the nix store.

@infinisil If that's better than this, then by all means go for it. Or if you think I could adjust this to incorporate some of your concerns, like length, then I'm happy to update this (with your guidance) and accomplish the same goal |

Motivation for this change
When using tools like
nixpkgs.lib.attrsets.mapAttrsToListand trying to build derivations where nix store file names
are to be created, set attributes like
".stack/config.yml"are invalid, so
sanitizeNixPathcleans them up to allowthem to be created in the nix store.
I did not include
-as a valid character because of rycee's reasoning here.If no prefix is provided, the string
safePrefix_is used.Things done
