update_payload: Regenerate protobuf with protoc 2.5

Goobuntu trusty uses protobuf 2.5.0 python modules, but the chroot uses
version 2.6.1. Protobufs compiled with protoc 2.6.1 (inside the chroot)
are not compatible with the python modules installed in trusty, so they
can only run inside the chroot. Nevertheless, protobufs compiled with
protoc 2.5.0 work with the new library version.

BUG=chromium:531884
TEST=`./paycheck.py` inside and outside the chroot with libprotobuf 2.5.0
