chore(whitby): enable zram swap r/5846
Whitby has a lot of memory, but I've still been fighting with the OOM
Killer trying to build a few big packages at the same time.  Besides,
it's generally a good idea to always have swap available even if
there's lots of memory for caching optimisation reasons[1], and zram
swap is efficient enough to basically provide bonus memory for free.
