Logging messages log to standard output [rt.cpan.org #82853]

Dist::Zilla seems to record log messages to standard output.  When using
dzil in a pipe (ex. dzil listdeps --missing | xargs cpanm), this can
confuse the tool reading from the other side of the pipe.  Would it be
possible to get Dist::Zilla to write to standard error instead?
