Update Makefile

[ewu63]

Purpose

During complex build, the importTest.py file is copied from the f2py directory but still executed from the old location. This is fine if the $PYTHONPATH starts or ends with a colon, as it means the current folder is added to sys.path. The import test will fail if the colon is not there.

To fix this, I have moved the importTest into the build directory, where the .so files are actually built. That way, we are testing in the same folder and there will be no import issues.
