#33041 reports a flaky test due to an apparent kernel bug on macOS 10.14 hosts.
So far, it appears that the kernel bug is not present in macOS 10.15.

The darwin-amd64-nocgo builder is currently configured to use macOS 10.14 rather than 10.15:
https://github.com/golang/build/blob/ef9e68dfbdfef06956e422b9b4dd7bec35064451/dashboard/builders.go#L2095

I would like to add a skip for the flaky test, but I don't want to skip the test on the -nocgo builder in perpetuity — I only want to skip the test on affected macOS versions. I could try to add some kind of complicated detection logic, but it seems much simpler to just upgrade the -nocgo builder to the latest host type.

Can we think of any reason not to use macOS 10.15 for the darwin-amd64-race builder as well? @toothrot @dmitshur

The test will remain flaky on the -nocgo builder until #37695 is addressed.
