media: MAINTAINERS: rectify ZR36067 VIDEO FOR LINUX DRIVER section

Commit 754f0f1b ("media: MAINTAINERS: change maintainer of the zoran
driver") added a new section in MAINTAINERS with an invalid file entry
and at the wrong place for alphabetic ordering.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains:

  warning: no file matches  F:  Documentation/media/v4l-drivers/zoran.rst

Point the file entry to the right location and move the section to the
right place in MAINTAINERS.
