FastPathAlloc: Skip if below clang 18.1.x

Fixes #301

We probably need to disable the arm64 android emulation as Google completely broke it.

How so? From what I can tell only the FastPathAlloc test is failing in the latest builds, which should be fixed with your updated Clang version check, right?

Google broke ARM64 emulation on x86_64 hosts a while a go. One workaround was to overwrite the qemu machine type, but I guess they changed this with the newer emulator version. Apart from this, it really bottlenecked the CI, because it was just terrible slow. The real solution is to virtualise it on an AArch64 platform.

I see, but the latest builds seem to run fine (minus the FastPathAlloc issue)?

Take a look at https://github.com/gnustep/libobjc2/actions/runs/11445118340/job/31841516643: MU2 emulator does not support arm64 CPU architecture[command]/usr/local/lib/android/sdk/platform-tools/adb -s emulator-5554 shell getprop sys.boot_completed
