Update Dockerfiles and kernel versions

In kernel 6.11 decl tag generation for kfuncs has been added. This
allows users to list all kfuncs built into the kernel via the vmlinux
BTF. This commit updates the versions.json to include kernel 6.11.

The current builder ships with pahole 1.24 which it gets from the
debian repository. This version does not support the new decl tag
generation. This commit updates the builder to build pahole 1.27 from
source.
