camera-calibration-parsers: disable support for python2

The package can't be built with python2 bindings since
libboost_python.so (which the bindings depend on) has been
disabled in Boost in OE upstream. Only python3 configuration
is supported nowadays.

Disable support for python2 in camera_calibration_parsers.
