client: do not insist on \n\n when parsing MGCP messages

The current implementation of mgcp_client.c requires MGCP
paragraphs to be separated wit a \n\n sequence. However,
when the client is used with servers other than osmo-mgcp,
the parapgraph may be formatted differently.

Also allow \n\r\n\r and \r\n\r\n as separator
