FIX #3566: redefine isfinite alias in sklearn

npy_isfinite from npy_math.h depends on the compiler used to build
numpy. If we build scikit-learn with a different compiler (e.g. MSVC
vs MinGW) this can cause link errors.

Therefore we redefine the isfinite macro in a scikit-learn specific header
file.
FIX: divide each row of the CM by the true support
