CI: Allow runUnittests to use 'expect' to run the tests

There seems to be a race condition between starting the asterisk
daemon and attempting to use 'asterisk -r' that can cause the
control socket file to not be created.  Since all of the Jenkins
slaves have 'expect' installed, the runUnittests script can use
it to start asterisk in the forground and issue the commands
interactively.  This is much more reliable and it can also make
startup errors more visible since they'll be in the Jenkins console
output.

If 'expect' isn't installed, the original daemon/asterisk -r
process is used.

Also added a "core show settings" before running the tests
and added "notice,warning,error" to the console log.
