sigrok-cross-android: Set host platform in PYTHON_FOR_BUILD

Unless _PYTHON_HOST_PLATFORM is set, setup.py will fail to detect
that this is a cross build, leading to dynamic modules being flagged
as "failed" because they don't load on the build system.

Set _PYTHON_HOST_PLATFORM in the same way it is done in the default
setting of PYTHON_FOR_BUILD.
