test: py: LD_PRELOAD the C++ standard library when using ASan
When the ASan runtime is linked using --as-needed, its dependency on the
C++ standard library is stripped. This results to a failure to properly
handled exceptions when a C++ dynamically loaded .so is used, as in the
Python unit tests that load the libcamera Python module:

The issue has been reported in [1] and so far remains unfixed. Work
around it by preloading the C++ standard library.
