tests: Add NOT_ZERO and NOT_NULL macros to the header file

This patch adds two macros into io_mock.h, so that they can be used
anywhere in tests. Common usage is to indicate a valid pointer, where
it doesn't matter what the pointer is, only matters it is not null.
Another case is to indicate a valid file descriptor, where it only
matters the descriptor is not zero integer.

New macros replace existing MOCK_HANDLE.

This patch corrects return value from __wrap_ioctl to be successful
by default. It used to be MOCK_HANDLE, but should be 0.
