Allow shortcuts to be pinned by unbundled chooser

Originally ShareSheet was part of android system, so shortcuts pinned by
ShareSheet are pinned by the system process. Since we are moving
ShareSheet into a separate module, this means shortcuts should not be
pinned by the system process, but by unbundled chooser process, when
that module is enabled.

This CL change the package name that pins the shortcut to corresponding
package in respect to whether intent resolver module is enabled.
