i965/blorp: Use R16_UNORM for Z16 surfaces.
Currently, all that matters is that we copy the correct number of bits,
so any format that has 16-bits of data will work fine.
Once BLORP begins handling format conversions, the sampler will need to
correctly interpret the data. We don't need a depth format, but we do
need the right number of components and data type (UNORM).
For Z16, this means using R16_UNORM.
