Subject: [PATCH] tools/openocd-rtt: also open GDB port

When using OpenOCD RTT (real-time transfer) for stdio with
`USEMODULE=stdio_rtt make ...`, it is no longer possible to debug
while being connected to stdio. By also opening gdb at RIOT's default
GDB port, `make debug-client` can be used to connect from GDB to the
OpenOCD instance providing stdio via RTT.
