Rather than try to file an oval, it
occurred to me that drilling at an angle will do the trick easily

Make sure to use a drill bushing regardless of the tool you eventually
choose. It'll keep that drill from wandering "downhill" or off your
intended mark. If tolerances are not too critical, you might be able to get
away with not using one... And if teh holes are large enough.
