makefs: warn that ffs sectorsize other than 512 may not work
newfs always sets sectorsize to DEV_BSIZE (512) and derives some other
values based on the number of 512-byte sectors per real sector. Similar
logic is required in makefs. Until that happens, emit a warning that
the image may be incorrect.
