Fix visibility on db image_member_find

Before this change, image_member_find was not paying any attention to
whether or not the requesting context was authorized to view the image
memberships. With this change, image membership results are always
limited to either images owned by the context tenant, or images shared
with the context tenant.

Fix up publicize_image unit test

The 'test_add_public_image_unauthorized' unit test wasn't checking
the 'publicize_image' policy as expected.

Replace it with new tests 'test_add_publicize_image_authorized' and
'test_add_publicize_image_unauthorized' which perform the check as
expected and verify both authorized and unauthorized code paths.

Fixes bug 1153670.
