travis-ci: check AsciiDoc/AsciiDoctor stderr output

`make` does not necessarily fail with an error code if Asciidoc/AsciiDoctor encounters problems. Anything written to stderr might be a better indicator for problems. Ensure that nothing is written to stderr during a documentation build. The redirects do not work in `sh`, therefore the script uses `bash`. This shouldn't be a problem as the script is only executed on TravisCI. Signed-off-by: Lars Schneider <larsxschneider@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
