Wildcard the clang version link in the post-install script in order to accomodate NDK 27 and 28

[marcprux]

This is needed because NDK 27 uses Clang 18 and NDK 28 uses 19. E.g., we want to be able to handle both these ANDROID_NDK_HOME locations:

~/Library/Android/sdk/ndk/27.0.12077973/toolchains/llvm/prebuilt/darwin-x86_64/lib/clang/18
/opt/homebrew/share/android-ndk/toolchains/llvm/prebuilt/darwin-x86_64/lib/clang/19
