box: add lua_call and lua_eval grant object types

Granting the execute privilege on the 'lua_eval' object enables
evaluaing any Lua expression via IPROTO_EVAL.

Granting the execute privilege on the 'lua_call' object enables calling
any global Lua function via IPROTO_CALL except:
 - Functions from the _func system space (see box.schema.func.create).
   Access to them is still governed only by the 'function' object type.
 - Built-in functions. We assume that all functions that were added to
   _G before loading user modules are built-in.

Note, after this change access_check_universe_object becoms unused so
it's removed (merged with access_check_universe).
