Allow running src/tools/msvc/mkvcbuild.pl under not Windows

This to allow verifying the MSVC build file generation without having
to have Windows.

To do this, we avoid Windows-specific Perl modules and don't run the
"cl" compiler or "nmake".  The resulting build files won't actually be
completely correct, but it's useful enough.
