[PATCH] perf build: Add libbabeltrace to build-test

'make build-test' doesn't test LIBBABELTRACE=1. It misses a building failure caused by commit 41840d211c51 ("perf config: Move config declarations from util/cache.h to util/config.h"), breaks bisect. Add LIBBABELTRACE=1 to build-test. Signed-off-by: Wang Nan Cc: Arnaldo
