Configure - "if options.run_gyp:" should be "if not options.run_gyp"

[tmcdos]

I am using Windows on my PC and I have an unrelated issue with the bundled Node so I have to patch one of the Node's internal JS modules (and hence must recompile node.dll)

When I tried to build electron-node-10.2.0 I got the error Failed to create vc project files.

After some primitive debugging I think that the reason for this error lies on the last line in configure. Instead of

if options.run_gyp:
  run_gyp(gyp_args)

it should be

if not options.run_gyp:
  run_gyp(gyp_args)
