Subject: [PATCH] url-lib: don't use --progress-bar if TERM=dumb (RHBZ#814713)

Basically, s390 is the only place I've ever seen TERM=dumb, and it's too
dumb to handle '\r', so --progress-bar produces waaaaay too much output.

The normal progress meter only prints something once per second, so
that's reasonable on terminals where '\r' doesn't work.
