test(macOS): skip the Keyboard tests on the Appium 1 leg

The tests synthesize key input through W3C actions, which the mac2
driver bundled with Appium 1 does not implement, so on the macOS CI leg
they could only fail. They keep running on Windows, where WinAppDriver
handles W3C actions, and on macOS builds with IsRunningAppium2, which
target a current mac2 driver. The infrastructure change that would run
them on macOS CI is split out for a separate pull request.
