buf.h: Fix declaration of unmapped_buf
For architectures with a small-data area, the __read_mostly section must
present at the object declaration.
(emaste note: This does not appear to have an affect within FreeBSD, but
may be needed by downstream projects that handle __read_mostly /
__section(".data.read_mostly") differently.)
