scripts: kernel-doc: Translate the "Output selection" subsection of OPTIONS

Aim: unified POD, user more satisfied, script better structured

The plurals in -function and -nosymbol are corrected to singulars.
That's how the script works now. I think this describes the syntax better.
The plurar suggests multiple FILE arguments might be possible. So this
seems more coherent.

Other notes:
- paragraphing correction
- article correction
