files: add helper function mkOutOfStoreSymlink
Using this function it is possible to make `home.file` create a
symlink to a path outside the Nix store. For example, a Home Manager
configuration containing

    home.file."foo".source = config.lib.file.mkOutOfStoreSymlink ./bar;

would upon activation create a symlink `~/foo` that points to the
absolute path of the `bar` file relative the configuration file.
