dumpstate OWNERS += smoreland@

I've changed it a lot in the past, for more cross-timezone owners.

I hearby certify that I understand the goals of dumpstate, including:
- making sure bugreports are as fast and as small as possible
- making sure all the code is not in the dumpstate process and is in sub-process commands, and not in the process itself, so that if there is an issue, it doesn't cause bugreport to fail
- keeping bugreports parcelable by the tools that already process them
