test-extension: flush diagnostic message to stabilize chg output

Since chg server may create new file object for the attached stdout,
procutil.stdout is not ui.fout and the buffered procutil.stdout data wouldn't
be flushed at all. That's why test-extension.t passes without modification
on Python 2.

# Disable the $CAP wire protocol capability.

if test -z "$CAP"
then
    echo "CAP environment variable not set."
