Fix broken quick previews in non-local volumes.

In MTP and media view volumes, quick view was failing to show
previews of media files because WebView does not have
permissions to access those files.

This patch restricts the volume types for which quick view supports
previews, so that broken <img> is not shown to users.

Note that |item.externalFileUrl| is filled if and only if files are on
DRIVE or PROVIDED volumes (see MultiMetadataProvider.prototype.get()),
so this patch changes behavior only on MTP, MEDIA_VIEW volumes.

BUG= 681517 
TEST=Broken <img> is not shown in MTP and media views.
TEST=Preview works on Drive, Downloads, ZIP archive and RAR archive.

Quick preview doesn't work for media files in ZIP archive.

Thanks for testing!

But if you mean "no preview available", it's different from this issue (this bug is for broken thumbnails). No preview issue is tracked in  Issue 685315 .
