Disable zlib compression in Blimp until crbug.com/637376 fixed.

There is a compiler/code optimization bug in zlib's SIMD implementation,
which will take time to investigate and fix. This CL restores
functionality in Blimp by disabling compression.

This CL can be rolled back once the root cause of crbug.com/637736
is addressed.
