Fix trace_to_text host binary generation

This CL fixed a bug in the proto_library.gni, that rebases
the proto file onto the |root_out_dir| rather than |root_build_dir|.
This causes an extra ../ in the invocation of protoc.
This also makes it so that the trace_to_text is built only for the
host but the binary is copied in the root build directory.

Perfetto - Performance instrumentation and logging for POSIX platforms

This project is meant to be built both as part of the Android tree and from a standalone checkout

For internal docs see this page

Supported platforms

Android is the platform targeted in the first milestones. Right now Linux desktop and OSX are maintained best-effort.

Contributing

This project uses Android AOSP Gerrit for code reviews and uses the Google C++ style. Currently targets -std=c++11.

You can use both git cl upload from Chromium depot tools or Android repo to upload patches.

git cl is quite convenient as it supports code auto-formatting via git cl format.

See https://source.android.com/source/contributing for more details about external contributions and CLA signing.
