Using fully qualified #include paths in g722 code.

WebRTC internal code should always use include paths that start
from the root of the project and that clearly identify the header file.

This allows 'gn check' to actually keep dependencies under control
because 'gn check' cannot enforce anything if the include path
is not fully qualified (starting from the root of the project).
