teuthology/scrape.py: Remove empty string in _get_service_types

Problem: the function grep returns a list contianing empty string which results in scrape.py throwing the warning "Misunderstood line: ". Solution: filter out empty strings before getting match with regex. Fixes: https://tracker.ceph.com/issues/62534 Signed-off-by: Kamoltat Sirivadhna <[email protected]>
