fix(hardened): restore podman compatibility on linux-hardened
Two breakages observed on first linux-hardened boot:
1. `podman run` failed because linux-hardened sets
kernel.unprivileged_userns_clone=0 by default (stock linux: 1).
Rootless podman requires unprivileged user namespaces. Restoring
the stock-kernel default via sysctl — this is a documented hardened
knob meant to be flipped back if you actually use rootless
containers. No-op on stock kernel.
2. "kernel does not support overlay fs: 'overlay' is not supported over
btrfs". Kernel overlayfs cannot use a btrfs subvolume as lowerdir;
podman needs fuse-overlayfs as the user-mode shim. ~10-30% slower
I/O than native overlay but works correctly and is the upstream
recommendation for btrfs-backed rootless storage.
