[PATCH] trace-cmd: Do not build or install traceevent plugins if libtraceevent exits

[Steven Rostedt]

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

The plugins for libtraceevent belong to libtraceevent. If libtraceevent is
installed on the system, then the plugins for libtraceevent should not be
built or installed by trace-cmd.
