    [MKISOFS] Fix Clang check for macOS platforms (#7037)
    
    * [MKISOFS] Fix Clang check for macOS platforms
    
    On macOS, CMAKE_C_COMPILER_ID is "AppleClang". While certainly Clang,
    this does not match the exact string "Clang" that is being checked for,
    and as a result the warning flags guarded thereby are not passed to the
    compiler. With this change CMake will recognize both Clang and AppleClang.
    
    * Update sdk/tools/mkisofs/CMakeLists.txt
