sigrok-cross-mingw: Lower Python version to 3.4 (Win XP support).

The last Python version to officially support Windows XP was 3.4.x.

We'll keep the Windows installers at that version for the time being,
until Windows XP support is no longer feasible (e.g. because important
sigrok requirements such as Qt, glib, or libusb drop XP suppport).
