babeltrace2: added first version, 2.0.1

Babeltrace 1 vs. Babeltrace 2

The Babeltrace project exists since 2010. In 2020, Babeltrace 2 was released.
Babeltrace 2 is a complete rewrite of the library, Python bindings, and CLI. It
is plugin based and offers much more features and potential than Babeltrace 1.

Because Babeltrace 2 is still a young released project, some distributions still
provide packages for the Babeltrace 1 project. Both projects can coexist on the
same system as there are no common installed files.
