Summary:
When patching the DUT to remove t0 peers, the test fails the DB comparison due to extra entries being added to APP_DB.

These entries only get added when generic patcher in SONiC (`config apply-patch`) is used to remove t0 from the DUT.

Ideally this should be fixed in `config apply-patch` code. This PR is a workaround for the issue since the extra entries are harmless and does not get used.

### Approach
#### What is the motivation for this PR?
`configlet/test_add_rack.py` is failing.

#### How did you do it?
Adding extra entries to ignore. These entries seems to be harmless and not used. However it is not understood why it is being added by `config apply-patch`.

Again, ideally this should be fixed in `config apply-patch` code. This PR is a workaround for the issue since the extra entries are harmless and does not get used.

#### How did you verify/test it?
Test no longer fails

#### Any platform specific information?
Broadcom platform is used for testing.

#### Supported testbed topology if it's a new test case?
