Redirect to STDOUT instead of STDERR: scripts/lb-wrapper

[deldesir]

I did not use a clean unit test for PR #88, making it pass with the original lb-wrapper from #86. I did not catch that the specific explicit redirection to STDERR introduced in #87 would prevent capturing lines with "downloading..." in them. So I revert back to the working state with this PR changing

eval "${XKLB_FULL_CMD}" \
     > >(while read -r line; do log "Info" "$line"; done) \
     2> >(while read -r line; do log "Warning" "$line" 1>&2; done) &
pid=$!
