Add logging of asciidoc/-tor errors

Add logging of the errors which asciidoc and asciidoctor output to their
stderr stream when converting asciidoc documents. Note that
asciidoctor's exit code may be SUCCESS even if there are ERROR messages
in its stderr output (tested with Asciidoctor 0.1.4 and 1.5.5).
Therefore log the stderr output whenever it is non-empty.

See #2399
