Adding install_headers target to install all headers
under 'include/traceevent' path, like:

  $ make DESTDIR=/tmp/krava prefix=/usr install_headers
  $ find /tmp/krava/ -type f
  /tmp/krava/usr/include/traceevent/kbuffer.h
  /tmp/krava/usr/include/traceevent/event-utils.h
  /tmp/krava/usr/include/traceevent/event-parse.h
