server/table: don't modify/delete path attributes for route server client
RFC7947 2.2 says
Optional recognized and unrecognized BGP attributes, whether transitive
or non-transitive, SHOULD NOT be updated by the route server
(unless enforced by local IXP operator configuration) and SHOULD be passed
on to other route server clients
