DOC: config: fix option spop-check proxy compatibility
The doc mentioned that spop-check option may only be used for backends.
However, option may be used in default and listen sections as well
according to the code. Let's fix the doc so that doc and code are
consistent to each other.
This could be backported to all stable versions.
