tests: fix "4 custom target depends extmodule" with Python 3.8+ on Windows

Browse Source 
Since CPython 3.8 .pyd files no longer look in PATH for loading libraries,
but require the DLL directory to be explicitely added via os.add_dll_directory().
This resulted in those tests failing with 3.8+ on Windows.

Add the DLL build directory with os.add_dll_directory() to fix them.

This was never noticed in CI because it only uses Python 3.7 and the
MSYS2 CPython still used the old behaviour until now.
