scripts/bloat-o-meter: Support comparing library archives
Library archives (.a) usually contain multiple object files so their output of nm --size-sort contains lines like: <omitted for brevity> 00000000000003a8 t run_test extent-map-tests.o: <omitted for brevity> bloat-o-meter currently doesn't handle them which results in errors when calling .split() on them. Fix this by simply ignoring them. This enables diffing subsystems which generate built-in.a files.
