Ubuntu 23.10 armhf ubuntu-cpc cloud image builds failing

[Philip Roche]

With the introduction of the 6.5 kernel for mantic two days ago we are seeing image build failures on the armhf builds.

cloud image builds for mantic for armhf following the roll to 6.5 kernel started to fail.

Recent build failures @ https://launchpad.net/~cloudware/+livefs/ubuntu/mantic/cpc/+build/496872 and https://launchpad.net/~cloudware/+livefs/ubuntu/mantic/cpc/+build/497411 (only viewable by Canonical Cloudware team) with failure `No kernel output for generic-lpae!` as a result of running

```
KVERS="$( (cd "binary/$INITFS"; ls vmlinu?-* 2>/dev/null || true) | (fgrep -v .efi || true) | sed -n "s/^vmlinu.-\\([^-]*-[^-]*-$FLAVOUR\\)$/\\1/p" )"
 if [ -z "$KVERS" ]; then
```

- see https://git.launchpad.net/livecd-rootfs/tree/live-build/auto/build#n643

Introduced in the 6.4 kernel and therefore now also in 6.5 there is no generic-lpae flavor anymore. it's just generic now.

It appears we have code @ https://git.launchpad.net/livecd-rootfs/tree/live-build/auto/build#n615 which sets the flavour for armhf to`generic-lpae` but others are `generic`.This can now be dropped for mantic+

All base mantic cloud image builds will fail to publish until this is resolved.
