treewide: fix `mkEnableOption` docs

`mkEnableOption` wraps its argument in a complete sentence with a
terminating full stop; an additional newline will add an incorrect
space before the end of the sentence in the rendered documentation,
and any additional verbiage that doesn't fit into the form "Whether to
enable [...]." is also incorrect. In the latter case, the description
can be overridden manually.
