SDL_mfijoystick.m: change TARGET_OS_OSX conditions to !TARGET_OS_IOS

TARGET_OS_OSX is in 10.12 SDK and newer.  Therefore, if building for
Mac OS X against an older SDK (e.g. 10.8), unconditionally including
SDL_config_iphoneos.h unconditionally defines SDL_JOYSTICK_MFI and
the build fails.

Also change the macOS version 11.0 checks to be more compatible with
older OS targets.
