workspace: update linux to 6.6.13

Now that Linux 6.6 is in LTS, let's switch to it. This also allows us to
drop one patch which has since been merged upstream.

As our kernel config hasn't been regenerated in quite some time I took
this opportunity to do so. No semantic changes to the existing config
were made, I just went through all new settings and set them to
appropriate values.
