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
