Remove the "doclusterread" and "doclusterwrite" buttons.
Cluster read is unconditionnally enabled for FFS since some years and
toggling "doclusterread" has no effect.
OpenBSD no longer support write clustering since the Dynamic Buffer
Cache went in, so there is reason to delay the call to bawrite(9).
