[bug#66888] [PATCH 1/2] gnu: babeltrace: Do not install bindings as egg.

[odion@efficios.com]

From: Olivier Dion <odion@efficios.com>

Oddly enough, bindings were now installed as an egg.  Fix this by
forcing setuptools to install individual files with
`--single-version-externally-managed'

*
gnu/packages/instrumentation.scm (babeltrace)[arguments]<#:make-flags>:
Pass it via DISTSETUPOPTS.
