kevinveenbirkenbachandClaude Opus 5.5 a63cbcb1f7 fix(apparmor): leave a read-only /proc/sys alone in teardown and restore ...

Fork run 41911075483 (feature/store-i18n 2fd6c6d310) lost both workspace
jobs, debian:13 and ubuntu:26.04, in make security-apparmor-teardown:

  common.sh: line 75: /proc/sys/kernel/apparmor_restrict_unprivileged_unconfined: Read-only file system

Inside the workspace container /proc/sys is mounted read-only, and the
write that #1371 added ran under set -e. A sysctl that cannot be written
now leaves the restriction as it is with a log line instead of failing
the teardown, and only a successful write records the previous value.
Restore keeps its record when it cannot write the sysctl back.

The tests call the helpers under set -euo pipefail like teardown.sh and
use /proc/sys/kernel/ostype as a sysctl nobody can write; both new tests
fail against the previous common.sh.
