Describe the bug

The mainline kernel (7.3+) now prints a structured report instead of the current verifier error format, see https://github.com/torvalds/linux/commit/ce7c9f6c599b

example:

    Verification failed: Register Type Safety: Unreadable register
    Reason:
      R0 has never been initialized on this path, so the verifier cannot use it as an input.
    At:
      insn 0
           | ^-- error: R0 is not readable

Failing job: https://github.com/cilium/ebpf/actions/runs/35109459957/job/104839480594
