i965/blorp: Bump the batch space estimate

Commit f938354362655a378d474c5f79c52cea9852ab91 recently increased the
alignment on vertex buffer data from 32 to 64.  This caused us to
consume a bit more batch than we were before and we now go over the
estimate by a small amount on certain blits on gen8+.  This commit bumps
then gen8 batch estimate by a bit to compensate.  Haswell and older
still seems to be well within the limit.
