Subject: [PATCH] giscanner: remove dependency on distutils.msvccompiler

It was removed with setuptools 74.0.0. Since we still depend on the
MSVCCompiler class use new_compiler() to get it some other way.

Remove any reference to MSVC9Compiler, which was for Visual Studio 2008
which we no longer support anyway.

Fixes #515
