awk macro: bugfix: :output file stream not closed.

In the case when the :output clause of the awk macro opens a
stream, it isn't closing it. Why don't we treat such a stream
uniformly with redirections.

* share/txr/stdlib/awk.tl (sys:awk-state :postinit):
If a file is opened for output, then don't just install
this file as self.output. Also place it into the self.streams
hash, identified by using the key (:outf <name>), just
like a (-> "name") redirection. This ensures that it will
be closed when the awk macro terminates. It's also potentially
useful in that output redirections referring to the name will
use the same stream.

* txr.1: Documented that streams opened by :output are
closed, and that they are treated uniformly with redirections.
