Small fixes for wacko CI environments

In the unusual case where the `runtimeDir` is not already created, we
should do so on `machine init`.

When starting gvproxy from podman, we now ensure it is running (for
applehv) but waiting for the unixgram socket to appear in the filesystem
before moving on.

[NO NEW TESTS NEEDED]
