Revert abiname and drop the abi check instead

Disable the module ABI check

Commit 8e1482b4 tried to bump the abiname to avoid incurring in failures due to the module ABI in Apertis not matching the one in Debian, but it had to be reverted as it introduced too much delta.

To address the ABI mismatch, simply disable the ABI checker, since Apertis is not committing to a stable module ABI at the moment.

The ABI bump will need to be reverted from pkg/target/linux-latest> as well.

This MR is based on !7 (merged).
