Title: [RFC] Fix clang empty report showed when warnings present.

Problem : Empty error is being showed even if there are warnings.
Cause : scan-build --status-bugs is working, but checked status is
that of the pipe, not scan-build's one.
Solution : Set option `pipefail` so that pipe status is that of the last
failing command.
