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.
