--manifest flag doesn't work on Windows

I tried this on the pyston macro-benchmarks.

PS C:\Users\gvanrossum\python-macrobenchmarks> py -m pyperformance list --manifest C:\Users\gvanrossum\python-macrobenchmarks\benchmarks\MANIFEST

Using run instead of list gives a similar traceback.

I tried it with the head of both repo pypeformance and python-macrobenchmarks and it worked. Can you try again? @gvanrossum

I expect it was fixed by #194.
