Revert 270872 "Move all callers of GetHomeDir() to PathService::..."

> 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.
