include/disas/dis-asm.h: Handle being included outside 'extern "C"'

Make dis-asm.h handle being included outside an 'extern "C"' block; this allows us to remove the 'extern "C"' blocks that our two C++ files that include it are using. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
