run_kfdtest.sh: Add --exclude flag to exclude additional subtests

Currently, using --gtest_filter will override any exclusions from
kfdtest.exclude. To add an additional test (or set of tests) to the
exclusion list dynamically, the --exclude (-e) flag will allow the user
to pass in a string of GTest-style exclusions to add to the list
generated by kfdtest.exclude

e.g. run_kfdtest.sh -e "*KFDLocalMemoryTest.*:KFDEventTest.*"
will use kfdtest.exclude, but will also exclude all LocalMemory and
Event tests
