Allow to execute some tests with a simulator or with a real rotator

To execute the tests with the installed Hamlib use the same long arguments
as rotctl, eg:
 bindings/python/test_rot.py --model {MODEL_NUMBER} --rot-file /dev/ttyUSB0 --serial-speed {BAUD}

To execute the tests from the build tree, add the path to the libraries
that you built, eg. from the root of the build tree:
 PYTHONPATH=bindings/:bindings/.libs/ ...your command...

bindings/python/conftest.py
