Useless -lonig when building using system libraries

[ancieg]

Why does you try to link the module with -lonig when JQPY_USE_SYSTEM_LIBS=1?
It's needed only for building libjq itself as I understand.

If I compile the module with link_args_deps = ["-ljq"] in setup.py:111, it even passes all of the tests in tests directory.
