x11-drivers/xf86-input-synaptics: Remove useless maintainer <descript…

…ion/>

Remove useless/redundant maintainer <description/>. It does not benefit
bug wrangling, and only wastes developer's time on reading it. Few tips:

- assignee/CC is implied by ordering, there is no reason to repeat it,
- we know that maintainer is maintainer (la la la la la),
- most of adjectives for maintainer are of no value and/or are obvious.
