tools lib traceevent: Shut up plugins make message

Getting rid of following build output:

  $ make O=/tmp/build/perf -C tools/perf/ install-bin
  ...
  make[3]: Nothing to be done for `plugins'.
  make[2]: Nothing to be done for `plugins'.
  ...

which triggers when traceevent library needs to be rebuilt, but we have
plugins built already.

Adding extra 'plugins' target with nop which is visible and triggers in
both Makefile parts (for detached output directory (O=...) the
traceevent Makefile spawns sub make for the build itself).
