[PATCH] ci: fix libabigail cache in GHA

[David Marchand]

In repositories where multiple branches run the ABI checks using
different versions of libabigail (for example, a 22.11 branch using
libabigail-1.8 and a main branch using libabigail-2.1), a collision
happens on the libabigail binary cache entry.
As a single cache entry is used, the content of the cache (let's say the
cache was built for libabigail 2.1) won't match what the branch wants to
use (in this example running the check for 22.11 branch requires
libabigail 1.8).
.ci/linux-build.sh then tries to recompile libabigail but it fails as
the packages used for building libabigail are missing.

Add the version to the cache entry name to avoid this collision.
