kfdtest: Fix problems finding kfdtest.exclude

When running run_kfdtest.sh through a wrapper script that sources
run_kfdtest.sh, kfdtest.exclude isn't found because $0 points to the
location of the wrapper script. User $BASH_SOURCE instead of $0 to
find the location of the correct run_kfdtest.sh script.
