Failures on [infra] Add xcodebuild/...XARM64 directories to the vm-kernel fileset

There are new test failures on [infra] Add xcodebuild/...XARM64 directories to the vm-kernel fileset.

The test

standalone_2/check_for_aot_snapshot_jit_test RuntimeError (expected Pass)

is failing on configurations

dartk-mac-release-arm64

The log:

--- Re-run this test:
python3 tools/test.py -n dartk-mac-release-arm64 standalone_2/check_for_aot_snapshot_jit_test

This is a dartk bot that builds runtime_kernel, so gen_snapshot should be available.

Note that the test is already failing in various ways across many configs:

For some reason, gen_snapshot is only in xcodebuild/ReleaseXARM64/clang_x64/ but not in xcodebuild/ReleaseXARM64/ (unlike dart which exists in both places):

For sure, and these errors need to be addressed also (in fact, may do so now), just noting that the failure case here is different than in the other cases and so is worth highlighting :)

(Well, the non-IA32 failures should be addressed, and the test should probably be marked skip on IA32 since there's no AOT mode there.)
