gtk: Make directory selection work with upload type

(<input webkitdirectory>).

Right now it hits NOTREACHED().
uploads have type = SELECT_UPLOAD_FOLDER.
They should be treated same as SELECT_OPEN_FILE and SELECT_FOLDER to
save the last opened directory path.

BUG=None
Test=Manually with a packaged app that has input element:
<input type="file" webkitdirectory id="directory"/>
