quote-stress-test: accept arguments to test via the command-line
 
When the stress test reported a problem with quoting certain arguments,
it is helpful to have a facility to play with those arguments in order
to find out whether variations of those arguments are affected, too.

Let's allow `test-run-command quote-stress-test -- <args>` to be used
for that purpose.
