Brad FitzpatrickandBrad Fitzpatrick af2f228a18 ipn/ipnlocal, types/netmap, tsnet: filter unsigned peers on delta path
aa5da2e5f2 (in the 1.99.x dev series, unstable) introduced some bugs,
only some of which were later fixed. This fixed another. As of that
change, tkaFilterNetmapLocked ran only on full netmaps through
LocalBackend.setClientStatusLocked and not peer upserts via new or
changed peers. The later ae743642d9 fixed a regression in the
Engine layer but didn't fix the tkaFilter code from re-running on
upserts.

This add a tkaFilterDeltaMutsLocked pass before
nodeBackend.UpdateNetmapDelta. For each NodeMutationUpsert whose
peer fails the same signature check tkaFilterNetmapLocked applies,
rewrite the upsert in place into a NodeMutationRemove targeting the
same node ID, so magicsock's per-mutation dispatch and
nodeBackend.peers both drop the peer, matching the prior full-netmap
semantics.

New tsnet tests added:

  - TestTailnetLockFiltersUnsignedDeltaPeer covers the new-peer
    case.
  - TestTailnetLockFiltersUnsignedDeltaPeerReplacement covers the
    existing-peer-replacement case, to an empty signature.
  - TestTailnetLockFiltersDeltaPeerWithInvalidSignature like above
    but with a bogus signature.

To avoid breaking downstream code, add deprecated aliases for all the
old names.
