Subject: [PATCH] refactor: replace boost predicates with absl

Replace boost::starts_with with absl::StartsWith in name_server_impl.cc
(3 sites) and boost::iequals with absl::EqualsIgnoreCase in
tablet_impl.cc (1 site), matching the convention used after the
boost::ends_with replacement in #4107. No behavior change.
