Bug 837715. Reduce compression rate for js source. r=benjamin

This cuts the time to compress gaia-email-opt.js from 0.63 seconds to 0.33
seconds.  The result should still be smaller (391K from 321K before) than the
compressing with snappy or lz4 (528K), but decompression time will be worse.
Fortunately, this will only penalize Function.toSource() which I think is an ok
trade off.
