Update dockerdoom with a TCP server for MacOS hosts

[briancain]

This commit updates the dockerdoomd project with a couple of features:

• TCP server for MacOS hosts (used through flags)
• Cleans up unix socket file on shut down when receiving a SIGINT

Note: I didn't add any way to override where the TCP server listens because at the moment it's pretty much hard coded in the dockerdoom source.
