[wrynose][PATCH 19/20] babeltrace2: inherit upstream-stable-release-point

[<daniel.turull@ericsson.com>]

From: Daniel Turull <daniel.turull@ericsson.com>

babeltrace2 maintains a branch per minor series (stable-2.0, stable-2.1)
and keeps the older one alive: 2.0.7 and 2.1.2 were released the same day
in July 2025, with 2.1.1 already out since April. So upgrades within a
major.minor are stable point upgrades per the OE-Core stable release
policy (ref-manual, "Stable Point Release Upgrades"). There is no written
policy document, so qualification rests on that branch structure and the
release contents below.

  https://docs.yoctoproject.org/dev/ref-manual/release-process.html#stable-point-release-upgrades
  https://github.com/efficios/babeltrace/tree/stable-2.1

Upstream keeps a ChangeLog with a per-release entry list. Both point
releases in the current series are fixes, tests and documentation: 2.1.2
(Jul 22 2025) is 13 commits, and 2.1.1 (Apr 14 2025) 10.

Already tracked this way on the OE stable branches, counting only bumps
since each branch forked: kirkstone took 2.0.4 -> 2.0.5 and scarthgap
2.0.5 -> 2.0.6. wrynose has taken none and sits at 2.1.2.
