Don't let harmless errorlevels from the "set" utility leak into proje…

…ct-specific build scripts

When using set to unset an environment variable that didn't previously
exist, set raises the errorlevel to 1. This was leaking into
project-specific scripts, causing them to think the build has failed.
We now clear the errorlevel after we finish setting environment
variables.

Fixes <http://webkit.org/b/50350> Windows builds mysteriously fail in
some configurations

* win/tools/vsprops/common.vsprops: Call "cmd /c" after setting
environment variables to get rid of any errorlevel that "set" set.
