Subject: lixPackageSets.*.lix: use buildPackages.python3 instead of
 python3.pythonOnBuildForHost

The former seems to exhibit fewer subtle issues breaking cross (in particular
static) builds, for reasons I have not yet understood.

(cherry picked from commit cf6821c8f84fe12f6e6120bcad28295ae2d9f291)
