Do not allow vintf_fragments for modules installed in the filesystem 

Soong defined filesystem does not have any logic to handle
vintf_fragments items, so those item should be used with vintf_fragment
modules instead. This change checks if there is any module installed in
the Soong defined filesystem and defines vintf_fragments property, and
raises error for those modules.

Bug: 322089980
Test: There is no diff between vintf manifests of generic_system_image
and aosp_cf_x86_64_phone
