gdbstub: Try unlinking the unix socket before binding
In case an emulated process execve()s another emulated process, bind() will fail, because the socket already exists. So try deleting it. Use the existing unix_listen() function which does this. Link qemu-user with qemu-sockets.c and add the monitor_get_fd() stub. Note that it is not possible to handle this in do_execv(): deleting gdbserver_user_state.socket_path before safe_execve() is not correct, because the latter may fail, and afterwards we may lose control.
