ctdb-tests: Add ctdb-config wrapper stub for event script tests

Create a shim helper around that simply invokes ctdb-config via its
real location.

This is needed because the event script tests set CTDB_HELPER_BINDIR
to the stubs directory because all other helpers used by event script
testing are currently stubs.
