Move unpack_aecdump to a more public location.

This tool is used downstream, so we want to christen rtc_tools as
a kind of api dir for tools. Tools in other locations should be
considered off limits.

I chose rtc_tools because video_quality_toolchain is already there,
which is also used downstream.

Bug: None
