Move all callers of GetHomeDir() to PathService::Get(base::DIR_HOME).

* Fixes GetHomeDir() for multi-profiles case on Chrome OS.
* Once user signs in on Chrome OS base::DIR_HOME is overridden with primary user homedir.
* Added content switch --homedir to pass that information to ppapi plugins since they run in a separate process and previous base::DIR_HOME override does not apply there.

This fix doesn't require checking for --multi-profiles switch
since user_id hash is known even without it.
