When we build custom 5.10.175-cip29 kernel
in one of the downstream layer we faced below error:

`BTF: .tmp_vmlinux.btf: pahole (pahole) is not available
 Failed to generate BTF for vmlinux
 Try to disable CONFIG_DEBUG_INFO_BTF`

hence install "dwarves" package as a dependency in sbuild-chroot
when we build custom kernels.

This commit message is rather specific and could be more generic, but i
think the patch itself is fine.

Stock debian kernels have CONFIG_DEBUG_INFO_BTF enabled so it is kind of
likely that pahole will be needed at build time.
