MAINTAINERS: Mark VME subsystem as orphan

Martyn Welch lost his access to VME hardware [1]; and Manohar Vanga has been
MIA since early January 2014 (his last message was [2]). Martyn admitted
that the subsystem is basically orphan, so mark it as such. As a bonus,
add CREDITS entries for the former subsystem maintainers.
