Use single quotes to make tests pass on Windows

Our use of test.pl requires single quotes for tests to the same way
across all platforms.

 This is testing the behaviour of the goto-inspect binary in case a binary
 is present, but no inspection option is present.
-
-This is labelled `winbug` to avoid running on windows because of issues with
-the empty string in line 3 (simulating the lack of an option) not working as
-it should (it is contrary to the behaviour of unix systems). The behaviour
-has been verified manually on a machine as working as expected, but getting
-the test to run automatically is a lot more involved, so we're opting to
-skipping this on that platform for now.
