cmd/callgraph: skip TestCallgraph on the windows-arm64-10 builder

We don't know whether this failure is due to a Go bug or a platform
bug, so we'll skip it on the one builder to reduce noise, but not the
GOOS/GOARCH as a whole. If we do not observe failures on other
windows/arm64 builders, we can perhaps chalk it up to a platform bug.
If we do observe failures on other builders, then we'll have more data
to investigate with.

For golang/go#50706
