SnapdragonCamera: Fix view video in Gallery the init state not pause

Gallery app package name has been changed. so Camera cannot find the
its name, and start with a common action "Intent.ACTION_VIEW" instead
which is only to play the current video.
Use a package name check for original Gallery and our new Gallery can
be better compatible, and can fix this issue.
