testimage/oeqa: Drop testimage_dump_host functionality

The intent behind these functions was to dump the system state when issues occured
but it has never really worked as we'd planned. Regular monitoring as the build
runs has largely replaced this as that allows a trend to be seen rather than a spot
value which was never really useful. The code is bitrotting and not functioning
correctly so drop it.
