incus: update to 6.15.0.

[duskmoss]

Hi, just making an update build for incus @dkwo

Removed umoci from the readme because 6.13 removed it as a dependency.

I will also make a PR to remove it from the void docs.

(if there is a consensus on whether we want this info in only one place, I can adjust this PR to remove the README or adjust void docs to not have the redundant information) @classabbyamp

Testing the changes

• I tested the changes in this PR: YES

[dkwo]

Some incusd tests are failing on aarch64 with Initialize LXC: allocating the container failed, but they also fail on master branch.
(I am fine deleting readme if all info is now in the docs.)

[dkwo]

it is failing TestContainerTestSuite/TestContainer_AddRoutedNicValidation and TestValidateConfig:

[duskmoss]

I don't think I can run the tests with a cross build right? Do you have any ideas on whats wrong?

Edit, just saw they also fail on master, to confirm you mean void-packages master, so it's not added with this update?

[dkwo]

Yes, it is void master. Can you rebase this pr on master? Perhaps even temporarily switch to native aarch64 ci, like first commit here #54013 ?
I wonder if these new failures are due to recent util-linux update, or my machine running newer coreutils, or else..

[duskmoss]

I don't have any aarch64 machines.

[dkwo]

I cannot reproduce on my other aarch64 machine, so perhaps this is related to newer coreutils (to be seen).
