node2nix: pull in patch to fix bin scripts with crlf line-endings

This is minor fallout from svanderburg/node2nix#302 which made node2nix
handle installing script bins itself (since npm stopped doing that
correctly).

It seems npm was doing line-ending normalization when installing these
files itself, so in addition to making all bins executable we now also
do a crlf to lf conversion on them if they are a script with a shebang.
