test-local-addresses: drop racy check

Browse Source 
The test would fail when addresses were being removed in parallel. In general,
the check is only valid when the machine configuration is static, which in
general isn't true.

CentOS CI (Arch Linux) fails in TEST-02-UNITTESTS test-local-addresses:

The logs show that there's a huge number of private addresses, probably from
some other test running in parallel.
