[PATCH 17/22] perf tools: Add build and install plugins targets

[Jiri Olsa]

Adding 'plugins' target along with the libtraceevent.a,
so plugins are built together with traceevent library.

Adding 'install-traceevent-plugins' Makefile install target,
instructing perf to install plugins into:
  $(HOME)/libexec/perf-core/traceevent/plugins
    - if installed localy under $HOME
  $(DESTDIR)/$(prefix)/$(perfexecdir)/traceevent/plugins
    - if installed globally
