hook: ensure stderr is flushed when an exception is raised, for test stability

Windows has had issues with output order in test-ssh-proto-unbundle.t[1] since
it was created a few weeks ago.  Each of the problems occurred when an exception
was thrown out of the hook.

Now the only thing blocking D2720 is the fact that the "abort: ..." lines on
stderr are totally AWOL.  I have no idea where there are.

# Disable the $CAP wire protocol capability.

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