win,msi: correct installation path registry keys

This is a port of 14db629.

Original commit message:

  Since install is per machine only, installation path should be stored
  in local machine instead of current user. The registry stores HKLM in
  different places for 32 and 64 bit applications, so the installer
  will not suggest the old path when upgrading from 32 to 64 bit
  version.

  Fixes nodejs/node-v0.x-archive#5592
  Fixes nodejs/node-v0.x-archive#25087
