Files app doesn't open in the Downloads folder by default since MyFiles
folder has been introduced. So the implicit expectation from ARC++
bridge that Files app would show Downloads is broken. This CL fixes it
by passing the Downloads folder when opening Files app.

NOTE: To have the whole workflow working other changes in Files app and
App Service are required and will be tracked on Issue:1090211

This issue was noticed in the Google Photos Android app, which shows a
link to open the Downloads folder after user has clicked "Save to
device" in a photo. See comments #10 and #11 in crbug.com/1090211#10

Test: Manually from Google Photos Android app
Bug: 1090211,607411
