Skip oclint installation on macOS due to dylib loading issue

The current oclint homebrew formula (24.11) has a hardcoded path to
libc++.1.dylib that doesn't exist on GitHub runners or most systems.

Error: Library not loaded: @rpath/libc++.1.dylib
  Referenced from: /opt/homebrew/Caskroom/oclint/24.11/oclint-24.11/bin/oclint-24.11
  Reason: tried: '/Users/lqi/Workspaces/ryuichis/Labs/oclint/build/llvm-install/lib/libc++.1.dylib' (no such file)

Skip oclint installation and version check on macOS until this is fixed upstream.
Tests that require oclint will be skipped on macOS.
