record: Use BSS section instead of per-CPU data

The .rtemsrwset section is used for the per-CPU data.  This section has
loadable content.  Place the ring buffers in the BSS section to avoid
large executable image sizes.

Not using the per-CPU data makes it possible to initialize the record
support earlier.

Update #3665.
