commit: https://git.buildroot.net/buildroot/commit/?id=9f2ca35998447a8107488925f5f60d371b46f047
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

We already have a mechanism for running stuff after the filesystem is
generated, and that's called post-gen hooks.

Use those hooks.

Note: for cpio (and unlike ext2 previously), the dependency chain was
correct, in that the post-target rule correctly depended on the image
rule. Nonetheless, we still want to fix it for consistency.
