extra-files: add udev rule for snap auto-import
This file has always been shipped by snapd, but we are about to remove it from there because it causes issues on recent classic systems.

Core22 has this: https://github.com/snapcore/core-base/pull/35 should we add something similar here too? Does udev/systemd from 16.04 even has the necessary support?
LGTM, thanks! Which is the PR removing from snapd?
It will come later, after the core snap has been released. By the way, how often does that happen?

No, it doesn't. In core22 that change was needed to workaround the security restrictions recently added to the udev unit file; but in previous Ubuntu distributions these restrictions are not there, so we can safely use unshare and call mount(). :-)
Has this been opened also in snapcore/core20 and snapcore/core18? I think those will need the fix too.

No, they already have their udev rules. Links in https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1966203/comments/13
