Add support for finding docker daemon from common socket paths (#263)

Caused by #260

act_runner will fail to start if user does not set `docker_host` configuration and `DOCKER_HOST` env. This PR adds the support for finding docker daemon from common socket paths so act_runner could detect the docker socket from these paths.

The `commonSocketPaths` is from [nektos/act](e60018a6d9/cmd/root.go (L124-L131))
