[system/partitionmanager/release/26.08] /: Be a tiny bit more lenient with KPMcore versions

Git commit 34515e478c68dc8b7e53b7b9a36994eb6bb4d91a by Heiko Becker.

Pushed by heikobecker into branch 'release/26.08'.

Be a tiny bit more lenient with KPMcore versions

The code comment also contains the motivation, but I add here that
it's an issue with CI I ran into when updating Gear versions after [1].
There was no longer a build of kpmcore with the new version and thus
partitionmanager failed to build.
