chromeos: Rename DriveDownloadHandler::GetDrivePath() to GetTargetPath(), make it return full path

'drive path' (e.g. drive/foo.jpg) extracted by drive::util::ExtractDrivePath() is only useful when dealing with DriveFileSystem.
In all other cases, including when opening files with FileManager, full path (/special/drive/foo.jpg) is more useful.

Achuith: REasonable to ask you to do file_picker_chromeos?  I think you know
that file better than I do.

Randy,

Sorry for being unclear.
What I wanted was your owner LGTM.

BTW, do you mind if I add some people from Chrome OS team to
chrome/browser/download/OWNERS with "per-file download_file_picker_chromeos.*"
and "per-file save_package_file_picker_chromeos.*"? (or simply "per-file
*_chromeos.*")
I think it will improve our productivity very much if currently there is no
people with the ownership who can review these file pickers.

First of all, LGTM :-}.

With regard to your OWNERS request, I'm in a bit of a bind.  Your request makes
sense, and I'd like to grant it.  But I don't want to add people to the OWNERS
files without confidence that they know the code well, and I personally don't
have confidence that I personally know the chromeos-specific code well, which
makes it hard for me to trust my own judgement that other folks know the code
well.  I've generally relied on Asanka and Achuith for reviews in those areas.  

So I think I'll continue my policy of trusting Asanka and Achuith WRT the
ChromeOS code and say: If either of them is willing to say to me that they
believe person X knows the chrome OS code well, I'm happy for that person to be
in the OWNERS file in the way you describe.  Is that ok by you?

My apologies for saying this while Asanka is OOO; ideally we would have 
resolved this while he was around.  But he'll be back in 2-3 weeks, and I
believe Achuith is available, so hopefully this won't interfere too much with
your moving forward.
