[PATCH v3 09/11] trace-cmd agent: Have agent work without vsockets available

[Steven Rostedt <rostedt@goodmis.org>]

From: "Steven Rostedt (Google)" <rostedt@goodmis.org>

Compile agent code without vsockets available to allow it to work with
networking. This includes allowing the ptp time synchronization protocol
to be used.
