Fix msvc build for localized versions of Visual C++

Look only at the non-localized part of the output from "vcbuild /?",
which is used to determine the version of Visual Studio in use. Different
languages seem to localize different amounts of the string, but we assume
the part "Microsoft Visual C++" won't be modified.
