package/libtraceevent: new package

Introduce the libtraceevent library, that is used to be bundled with the
trace-cmd tool. This library is now used by several tools and libraries
such as trace-cmd, libtracefs and rtla.

To build with meson, this package requires to disable documentation
generation, and since this is not possible add a local patch pending
upstream that adds -Ddoc=false support to libtraceevent.

+	  libtraceevent is a library that interfaces with the ftrace
+	  subsystem in the linux kernel.
+	  It used to be bundled directly in the trace-cmd
+	  tool, but it was eventually extracted so that it can be used
+	  by multiple other tools and libraries, such as libtracefs and
+	  rtla.
