python: force off_t size to 8 to enable large file support

If DISTRO_FEATURES contains "largefile", force the size of off_t to 8 as
a workaround for having ac_cv_sizeof_off_t=4 on 32-bit systems. In
future we will likely drop the value from the site file, but for now
this is a slightly safer fix.

Fixes [YOCTO #6813].
