python-numpy: Ensure `_npy_scaled_cexp{, f, l}` is defined when needed

With update of Numpy to the latest version we've got one change which
breaks Numpy compilcation in some cases.

This change back-ports upstream fix from:
https://github.com/numpy/numpy/pull/9740

+Subject: [PATCH] BUG: Ensure `_npy_scaled_cexp{,f,l}` is defined when needed.
+
+The `_npy_scaled_cexp{,f,l}` functions were previously only defined when
+the npy_cexp fallback functions were needed, but they are also called by
+the npy_csinh and npy_ccosh functions.
