On Windows, the `os.Process.Signal` method returns an error when sending `os.Interrupt` (SIGINT) because it isn't implemented. This causes test servers in the `testutil` packages to break on Windows. Use the platform specific syscalls to generate the SIGINT instead. The agent's signal handler also did not correctly handle the Ctrl-C because we were masking os.Interrupt instead of SIGINT.
