[snap] add daily USN check

This workflow will download the current snaps published in the `candidate`
channel for all architectures and check them for packages with published
Ubuntu Security Notices. If it finds one, it will trigger a build of the
snap recipe:

https://code.launchpad.net/~subsurface/+snap/subsurface-stable

This will rebuild the snap with patched packages and publish it to the
`candidate` channel.
