media: MAINTAINERS: adjust entry to zoran driver movement

Commit 2a0c2806 ("media: zoran: move to mainline") moves the zoran
driver from the staging to the media subsystem, but does not adjust the
entry in MAINTAINERS.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Repair this file reference in ZR36067 VIDEO FOR LINUX DRIVER.
