[Pkg-chromium-maint] Missing build-deps for chromium 35.*

[Sven Hartge]

Hi!

I tried to recompile chromium 35.0.1916.99-1 from experimental for 32bit 
in my system using cowbuilder.

I found out the following packages are missing from the build-depends:

protobuf-compiler
ninja-build
gperf

You got libprotobuf-dev but since this does not depend on 
protobuf-compiler, /usr/bin/protoc is missing.

Grüße,
Sven.
