component: Avoid adding to the global stream metatable

This allows component and client connections to be made side-by-side.
Previous to this change, loading this connection module would break the
ability to make client connections, due to overriding stream methods such as
:reopen() and :reset().

A next step would be to share the methods that the two connection modules have
in common.
