doc: no support for CPython faulthandler module

[mike-hunhoff]

The CPython faulthandler module installs fault handlers for the SIGSEGV, SIGFPE, SIGABRT, SIGBUS, and SIGILL signals. Unfortunately, our experience shows that this level of OS/process manipulation destabilizes the Java process that is running Ghidra + Ghidrathon, often resulting in a crash (SIGSEGV). For the time being, we need to document that Ghidrathon does not support the faulthandler module (and likely never will). Python modules that use the faulthandler module, e.g. pytest, should be configured to disable it, if possible. If the faulthandler module cannot be disabled then Ghidrathon does not support the Python module(s) that use it. We should also note that, in general, Ghidrathon's behavior for this level of OS/process manipulation is undefined, at best.

Known Python module using faulthandler:

Module	How to disable?
pytest	use -p no:faulthandler at invocation; see here
