MAINTAINERS: Remove Jacek Lawrynowicz as intel_vpu maintainer

Remove myself from the intel_vpu driver maintainer list as I'm
moving to another company. Time to let someone else deal with
the NPU bugs while I pretend to know what I'm doing elsewhere!

Thanks to everyone for the great collaboration (and for putting up
with my creative interpretations of what "minor fixes" means).
