Delay import of distutils.msvccompiler to avoid warning on non-Windows.

*Importing* distutils.msvccompiler works on non-Windows systems, but
triggers a pointless "warning" (using distutils' own logging system;
"Can't read registry etc.")  Delay the import so that other uses of
distutils.misc_util are not affected.

When running distutils commands, the verbosity is set by default to 1
(`self.verbose = 1` in distutils/dist.py) so the warning does get
displayed.

To trigger the warning, subclass e.g. build_ext, override its
finalize_options method, import numpy.distutils.misc_util from there,
and then pass the new build_ext as cmdclass to setuptools.setup().
