[Merge] ~mwhudson/livecd-rootfs/+git/livecd-rootfs:lang-layer-names into livecd-rootfs:ubuntu/master

[Michael Hudson-Doyle]

The proposal to merge ~mwhudson/livecd-rootfs/+git/livecd-rootfs:lang-layer-names into livecd-rootfs:ubuntu/master has been updated.

Description changed to:

This started out because I wanted to make the per-language layers have more predictable names to make life in subiquity easier but every time I looked at the implementation of remove_packages_from_seed_regexp my brain fell out of my ears so I rewrote it all in a way that's hopefully a bit easier to read.

https://launchpad.net/~mwhudson/+livefs/ubuntu/impish/test/+build/291290 is a test build with this change (it's only just started at the time of writing)
