Remove unnecessary workaround to vogar escaping issue

Vogar didn't handle arguments for the target (i.e. after --)
properly if they had characters that affect shell parsing, e.g.
spaces. In order to work around it the tools/run-jdwp-tests.sh
script added some extra quotes that now cause it to break. This
simply removes those quotes.
