`pkg/dartdev/test/commands/compile_test` flaky -> RuntimeError on `unittest-asserts-release-mac-x64` about sdk

[bkonyi]

In particular, compile - Compile and run executable from signed dartaotruntime is failing.

It looks like the failure is caused when attempting to generate a dill file using gen_kernel_aot.dart.snapshot with a signed dartaotruntime. Running the snapshot with an unsigned runtime works, and running dartaotruntime --help does as well. However, running the AOT snapshot with the signed runtime results in the process being SIGKILL'd. Signing the AOT snapshot doesn't change anything.

Here's the output from the system logs:
