kernelshark: add ftrace gui viewer

The trace-cmd source includes a graphical trace viewer, but we
don't want to make the trace-cmd recipe depend on gtk+. This
patch adds a second recipe in the meta/recipes-kernel/trace-cmd
directory which uses the trace-cmd SRCREV and RDEPENDS on trace-cmd
to ensure compatibility.
