no longer necessary, things are handled in ./server Makefile
take MaxScale_test.cnf from srcdir, no need to copy it over to builddir
only set path to errmsg.sys if needed (and use the correct parameter)

and install it in a non-default place) we need to set the path
kill maxscale daemon by pid, not name, and check for pid file
to detect successful start
