[Buildroot] [git commit branch/2022.05.x] docs/manual/prerequisite.txt: add findutils in dependencies

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=b1ea4af36a6f3e760280316c952e2313bf76c566
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2022.05.x

The "find" and "xargs" commands, from the "findutils" package are used
during the build process. See for example [1].

Even if it's a quite common package which is almost sure to be present
on the host, it should be listed here. When writing new recipes, hooks
and scripts, it is generally safe and portable to restrict to the
host dependencies listed in those prerequisites.

This commit just add the missing "findutils" package in this list.
