ui: look before you leap on sys.stderr.closed (and look nicer)

f83291e5643e introduced a fix if sys.stdout.closed does not exist.

This change uses a getattr with default instead of hasattr (which just calls
getattr) and accessing the attribute.

Additionally it applies the same fix for sys.stderr.closed as this is not
available in the bpython shell (reported by Roger Gammans).

# The converter does not currently handle patch conflicts very well.
# When they occur, it reverts *all* changes and moves forward,
# letting the conflict resolving patch fix collisions.
# Unfortunately, non-conflicting changes, like the addition of the
# "c" file in p1.1 patch are reverted too.
# Just to say that manifest not listing "c" here is a bug.
