This is required for modules that may return a non-zero `rc` value for a
successful run, similar to #24865 for Windows fixing **win_chocolatey**.
We also disable the dependency on `rc` value only, even if `failed` was
set.
Adapted unit and integration tests to the new scheme.
Updated raw, shell, script, expect to take `rc` into account.

This change corrects problems reported by the `yamllint` linter.
Since key duplication problems were removed in 4d48711, this commit
mainly fixes trailing spaces and extra empty lines at beginning/end of
files.
