Subject: [PATCH 14/14] tools build: Disable default check for libbabeltrace

Remove libbabeltrace check from default features set, because the
requested version is not released yet in most distributions. We'll
enable later.

Calling libbabeltrace check manually via feature_check
before $(feature-libbabeltrace) is used.
