perf build: Disable libbabeltrace check by default
Disabling libbabeltrace check by default and replacing the
NO_LIBBABELTRACE make variable with LIBBABELTRACE.
Users wanting the libbabeltrace feature need to build via:
$ make LIBBABELTRACE=1
The reason for this is that the libababeltrace interface we use (version
1.3) hasn't been packaged/released yet, thus the failing feature check
only slows down build and confuses other (non CTF) developers.
