`ContainerDaemonSocket` is stored on a shared struct and was mutated to a default value when empty, which trips the data race detector as a mutation of shared state without any synchronization. However as all codepaths would be setting it to the same value in the mutation, here's no functional bug. This commit prevents the "false positive", but it also centralizes the default value for a slightly better programming practice.
