  [Driver] Enable stdlibxx-isystem test on Windows

With `%/t`, we can now compare `-###` output against the installtion dir
without backslash escaping getting in the way. Having to check against
the doubled-up backslashes is ugly, but it's the pattern used in lots of
tests (including for things like debug info where an `-###` alternative
that didn't escape backslashes wouldn't help).
