Fixes two potentially device/kernel specific, or flaky bugs:
1. Java interface checking by name seems to cache the lookup, resulting
in interface address checks occasionally failing (on delete).
2. Link-local addresses appear to be added on all links for some set of
kernels and devices.
This patch addresses both by only checking that the requested address
was added via a address-based NetworkInterface lookup.
Bug: 72950854
Test: Ran on sargo-eng on qt-dev/HEAD
Test: Manually verified that the addresses are indeed added/removed
