update_engine: Adds BROTLI_BSDIFF operation

Brotli compression creates on average 10%-20% smaller output than bzip2
in addition to having faster decompressor. With recent changes in bsdiff
to compress the its patch with brotli, we can use it in the
update_engine as a new operation BROTLI_BSDIFF. This operation will be
turned on in minor version 4. However, this CL only adds support for it
in the client. It will not generate BROTLI_BSDIFF operations yet.

BUG= chromium:783437 
TEST=unittests pass for both update_engine and update_payload;
'brillo_update_payload {generate|verify}' passes;
'scripts/paycheck.py payload.delta' passes;
