test: fix acceptance tests on Apple Silicon Macs

We observed sporadic compilation or bytecode issues
on Apple Silicon Macs.

According to golang/go#42774,
the env variable `GODEBUG=asyncpreemptoff=1` works around
the issue by disabling asynchronous preemption of
goroutines.

This might impact garbage collection performance, but restores
the same level of reliability to locally running tests as
when run in Docker on an Intel based Mac.

The `GODEBUG=asyncpreemptoff=1` variable is set when creating
the Docker container for running tests locally, and applies
to all Go code, including `go vet`, for which we also observed
sporadic issues.
