It's been failing regularly on Windows/x64 , example at https://build.golang.org/log/6d9c92c981b5fb561f33eda94a418ee2ec05a846

--- FAIL: TestDialerDualStack (4.91s)
    dial_test.go:664: dial tcp 127.0.0.1:4306: i/o timeout

Same as #12052, dialClosedPort on Windows also takes a bit long time?

      net: Increase the acceptable delay in TestDialerDualstack

This may fix the flakiness on Windows/x64, assuming that it's actually
due to a variance in the connection time which slightly exceeds 100ms.

150ms + 95ms = 245ms, which is still low enough to avoid triggering
Happy Eyeballs (300ms) on non-Windows platforms.

Updates #12309
