explicitly free codecs in mgcp_rtp_conn_cleanup()

There are allocated bits in conn->end.codecs[], free them.

This is not fixing a memleak, since mgcp_rtp_conn_cleanup() is currently only
called from mgcp_conn_free(), which soon after frees the conn; the conn serves
as talloc parent for the codec strings freed in this patch.

The rationale: it is better style to explicitly free them, to also guard
against future callers of mgcp_rtp_conn_cleanup() which might expect complete
cleanup.
