commit: https://git.buildroot.net/buildroot/commit/?id=80168aa3c65d019df1619fc31e72c98d279e80c1
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Currently, when a package needs to modify files it inherits from its
dependencies, because they contain paths, we can only do that in a
pre- or post-configure hook.

However, whatever is done as part of those hooks, will be accounted
to the package itself, and thus will trigger file-overwrite detection.

So, we need a way to be able to actually modify files before we
start monitoring changes in those files.

We introduce a new set of hooks that an individual package can set,
or that a package infra can set, and that are called right before
we snapshot the state of target, and host (to which staging belongs),
