[Buildroot] [PATCH v4 3/4] lttng-babeltrace: add host Babeltrace as host utility

[Philippe Proulx <eeppeliteloop@gmail.com>]

Although Babeltrace is available for all major Linux distributions, some
of them have a quite old version of this project.

Changes v3 -> v4:
  - Config.in.host: remove paragraph about the fact that you can
    transfer traces on the host and use a host Babeltrace (as requested
    by Yann).
