Local builds are placed in wrong directory

[joepie91]

On Linux, the npm package contains a Linux build in...

build/linux/Release/glfwJS.node

... however, when building the package locally on post-install, the build ends up in...

build/Release/glfwJS.node

... and the other contents of the build folder seem to get wiped out. This produces the following error when attempting to use glfwJS:

[nix-shell:~/projects/ui-experiment]$ node example.js 
node:internal/modules/cjs/loader:936
  throw err;
  ^

Error: Cannot find module '../build/linux/Release/glfwJS.node'

(Note that I cannot use the build included in the npm package for using-a-weird-distro reasons, but presumably this affects any case where the build gets carried out locally for any reason)
