Fix permission issue in legacy shortcut

When building legacy shortcut, Launcher calls
PackageManager#resolveActivity to retrieve necessary permission to
launch the intent.

However, when the source app wraps an arbitrary intent within
Intent#createChooser, the existing logic will fail because launching
Chooser doesn't require additional permission.

This CL fixes the security vulnerability by performing the permission
check against the intent that is wrapped within.
