Update traffic annotations.xml.

Updating annotations.xml is requested before landing any CL that changes
an annotation. To do the tests fast on trybots, only .mm and .cc files
are checked. Also the tests do not cover ChromeOS and ios specifc code.

This annotation has been moved to ChromeOS specific code by a build file
change, hence gone unnoticed by the trybots. This is a typical case that
the FYI bot gets the problem and fires an error for manual update of
annotations.xml

Annotation is marked deprecated as we still do not support ChromeOS in
annotations.xml.
