Skip clearing verification for apps marked with SystemConfig <app-link>

If a system app misconfigures their AndroidManifest.xml and does not
declare autoVerify="true" in any of their intent filters, they will
lose app link verification when their app is updated from the version
on the system image.

This means the app will stop automatically opening when a web link is
is opened by the user.

To prevent this, ignore verification info clear requests when the
package being cleared is in the linked apps set.

Bug: 175139501

Test: manual, verify by updating <app-link> configured app
