pssh-box.py needs Python protos, which we were not building. It also
needs to have those protos installed properly.
This fixes generation of Python proto interfaces and fixes the install
targets to put those protos where they are needed. This also updates the
documentation to match.
With the update, the script needs to be launched from
out/{Debug,Release} directory.
Also updated docs to make it clear how to use the tool.
Fixes#538.

This script can be used to parse and generate PSSH boxes. This
serves two purposes:
* Parse PSSH boxes into a human readable format.
* Take several arguments to generate PSSH boxes.
This is also able to parse Widevine and PlayReady PSSH data and will
print the parsed data instead of the data as binary. This can also
generate Widevine PSSH data instead of having the PSSH data passed
as an argument.
