win: fix custom actions on Visual Studio != 2013

This is a port of joyent/node@16bcd68dc5f449c331499ced22aa626dbb2cdefc .

Original commit message:

  The original change that added support for running custom actions
  during the install process
  (joyent/node@e7c84f82c730bddb7450dc56065aab11b93ffd30) assumed that
  Visual Studio 2013 is used to generate the installer file.

  However, that is not always the case, and older versions of Visual
  Studio should allow users to generate Windows installer files. This
  change makes the custom actions visual studio project use the visual
  studio version that is found by vcbuild.bat.
