Motivation for this change

Currently, using VSCode extension remote-ssh with NixOS host requires an annoying patch. This client-side patch changes the package so the host node (as found by which node) is always used.

Main limitation: prior to patch, you could remote-ssh to Ubuntu without nodejs_12 installed, and it would work by locally installing node binary. With this patch, you'll need to first sudo apt install nodejs or install nodejs in userspace via another means.

Benefit: as long as a NixOS box has nodejs-12_x installed, it now works out-of-the-box with remote-ssh. As does any other old OS, so this effectively fixes microsoft/vscode-remote-release#103.

Closes nix-community/home-manager#939
