mingw: really handle SIGINT
Previously, we did not install any handler for Ctrl+C, but now we really want to because the MSYS2 runtime learned the trick to call the ConsoleCtrlHandler when Ctrl+C was pressed. With this, hitting Ctrl+C while `git log` is running will only terminate the Git process, but not the pager. This finally matches the behavior on Linux and on macOS.
