Fix getStorageVolumes to return public volumes visible to

userIdSharingMedia with.

In ag/16708639, getStorageVolumes was modified to return volumes
mounted on the calling user.
Clone profile is an exception to this rule, as by definition, it
should access the public volumes available to its parent user.
To fix this we allow a volume to be returned if:
1. Its a public volume and
2. Its visible to the userId the calling user shares media with.
