nanobsd: Offset code partition to a track boundary
Ensure the primary and secondary code partitions start at a proper track
boundary by applying a NANO_SECTS offset in bytes.
While track-boundary alignment is largely obsolete on modern storage,
this change maintains compatibility with current images (legacy). A
future commit will transition to 1 MiB alignment boundaries.
