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.

Note:
download_prefs.cc still uses GetHomeDir() in its DownloadPathIsDangerous() check.
// Consider downloads 'dangerous' if they go to the home directory on Linux and
// to the desktop on any platform.
In this context correct behavior is to use "real" base::GetHomeDir() and not "virtual one" base::DIR_HOME.
Since latter is remapped to some test dir in tests, in some subfolders in Chrome OS etc.
