block/null: Expose read-zeroes option in QAPI schema 

Commit cd219eb1e5 added the read-zeroes option for the null-co and
null-aio block driver, but forgot to add them to the QAPI schema.
Therefore, this option wasn't available in -blockdev and blockdev-add
until now.

Add the missing option in the schema to make it available there, too.
