selftests: mptcp: add cfg_do_w for cfg_remove 



In some testcases, we need to slow down the transmitting process. This
patch added a new argument named cfg_do_w for cfg_remove to allow the
caller to pass an argument to cfg_remove.

In do_rnd_write, use this cfg_do_w to control the transmitting speed.
