fix unused variable warning

[mizvekov]

compiling 3.0.0p2 with clang, I get the following warning:

catch2/internal/catch_run_context.cpp:465:31: warning: unused variable '_' [-Wunused-variable]
        FatalConditionHandler _;
                              ^

Needs something like [[maybe_unused]] or similar, possibly in a way that handles old standards / compilers.

What compiler+platform are you using?

[mizvekov]

clang 11.0, on two profiles, targeting x86_64 mingw32 and also msvc.
