systemd: set zstd as default PACKAGECONFIG
Upstream supports zstd compression now as an alternative to zlib or xz.
zstd is only slightly larger than xz but is significantly faster. This
makes it a better candidate for the journal. Enable it in systemd
instead of xz.
Add an exemption for witherspoon to continue using xz instead. Having
both zstd and xz support built into the image puts us over the flash
limit and we currently need xz for phosphor-debug-collector.
