Pass USE_FUSE2 define to apfs-fuse build under macOS

On my mac, with the lastest OSXFUSE version (3.11.2), the version of FUSE that is installed is actually 2.9.7:

$ pkg-config --modversion osxfuse
2.9.7
$ pkg-config --modversion fuse
2.9.7

so compiling apfs-fuse without defining USE_FUSE2 breaks with the following output (which is the same as for https://github.com/sgan81/apfs-fuse/issues/118):

The fix here is to specify the same target_compile_definitions for builds with APPLE defined as for those without USE_FUSE3=ON would otherwise.
