perf intel pt decoder: clang has no -Wno-override-init

So set it only for other compilers, allowing us to overcome yet another
build failure due to an inexistent clang -W option:

error: unknown warning option '-Wno-override-init'; did you mean '-Wno-override-module'? [-Werror,-Wunknown-warning-option]
