Update golang to add "windowsservercore" variants

[tianon]

See:

• Officially exempt "microsoft/windowsservercore" and "microsoft/nanoserver" from the "non-official images" exclusion #2051
• Add Windows Dockerfile golang#92
• Add "windowsservercore" variant golang#106
• Fix some minor bugs in update.sh and add windowsservercore variants for 1.5 and 1.7 golang#108
