Allow disabling SSH

The intent behind this commit is to add the dropbear service, monitor
the Enabled and Running properties, and then update the
dropbear.socket to allow disabling/enabling SSH.

Tested:
1.
busctl introspect xyz.openbmc_project.Control.Service.Manager /xyz/openbmc_project/control/service/dropbear
 xyz.openbmc_project.Control.Service.Attributes       interface
 .Enabled                property  b    false  emits-change writable
 .Masked                 property  b    false  emits-change writable
 .Running                property  b    true   emits-change writable

 Open a new SSH connection:
 sudo ssh username@<IP>
 Successfully connected

2.
busctl set-property xyz.openbmc_project.Control.Service.Manager /xyz/openbmc_project/control/service/dropbear xyz.openbmc_project.Control.Service.Attributes Running b false

busctl introspect xyz.openbmc_project.Control.Service.Manager /xyz/openbmc_project/control/service/dropbear
 xyz.openbmc_project.Control.Service.Attributes       interface
 .Enabled                property  b    false  emits-change writable
 .Masked                 property  b    false  emits-change writable
 .Running                property  b    false  emits-change writable

 Open a new SSH connection:
 sudo ssh username@<IP>
 ssh: connect to host <IP> port 22: Connection refused
