If mount and password are both TCP use TCP-client instead of NTRIP-server

[Jef239]

To use rtkdirect, RtkBase must be connected as a TCP client, and not as an NTRIP server.

So I modified run_cast.sh so that when mountpoint and password are both equal to TCP, the connection goes as tcpcli:// and not as ntrips://
