[release/1.1 backport] runtime/v1/linux/proc/io: io race

[thaJeztah]

backport of #3153 for the 1.1 branch

This code moved around between 1.1 and 1.2 (with the introduction of the V2 runtime), so I applied the patch manually;

git format-patch --relative HEAD~ 
git checkout -b 1.1_backport_issue_3118 upstream/release/1.1 
git am -p3 --reject 0001-runtime-log-IO-error-when-copying-output-streams.patch
git am -p3 --reject 0002-runtime-guard-Close-until-both-streams-are-complete.patch

hm... CI is not triggered on this PR for some reason

LGTM

I'll rebase/push again once #3157 is merged to have CI run 👍

edit: never mind, looks like it just took a bit; it's running now 😅
