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

[Jiri Olsa]

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.
