epee: update 'http_server_handlers_map2.h' macros to use fully qualified names

quick patch which fixes the issue where if you use some macros from `http_server_handlers_map2.h` you have to be in the `epee` namespace or it doesn't compile. Now can remove `using namespace epee;` from header file `core_rpc_server.h`, which caused a couple of name qualifying mistakes
