Force Attach() to send a SIGWINCH and redraw
Basically, we want to force the application in the container to
(iff the container was made with a terminal) redraw said terminal
immediately after an attach completes, so the fresh Attach
session will be able to see what's going on (e.g. will have a
shell prompt). Our current attach functions are unfortunately
geared more towards `podman run` than `podman attach` and will
start forwarding resize events *immediately* instead of waiting
until the attach session is alive (much safer for short-lived
`podman run` sessions, but broken for the `podman attach` case).
To avoid a major rewrite, let's just manually send a SIGWINCH
after attach succeeds to force a redraw.
Fixes #6253
