Support enabling vsock connections with a launcher flag.

vsock connections are a guest/host communication channel.

This is gated on a flag as it requires user access to /dev/vhost-vsock
on the host as well as guest kernel support, neither of which are
guaranteed by Cuttlefish at the moment. The flag is enabled when the
capability "vsock" is detected.
