Allows user to specify an optional ZFSBOOT_POOL_SIZE for their zroot
The default is to create a zroot that consumes the whole disk because if
used with geli(8) this makes sense.
Without geli(8), I like to keep my data pool separate from my system
pool.
This is different than ZFSBOOT_BOOT_POOL_SIZE which is named bootpool.
