description:
Add a sectorsize parameter member in struct ib_params and use it
where sector size (disk block size) is required, instead of
DEV_BSIZE constant which means device I/O block size.
"Looks reasonable" from dholland@, and fixes tools installboot(8)
on Cygwin where DEV_BSIZE != 512 as mentioned in PR toolchain/42555.
