[DistroKit] [PATCH 2/2] kernel: backport modules.builtin.modinfo permission fix

[Michael Olbrich]

With Linux kernel 6.18 and some architectures and objcopy versions
modules.builtin.modinfo is executable. This makes no sense and our
sanity checker complains about it.

Backport the fix for this from PTXdist master.
