ia32-base.inc: Use a weak default assignment for kernel provider and version

Using the default assignment operator (?=) requires the including recipes
to ensure to assign the Linux kernel provider and version prior to including
ia32-base.inc. By use the weak default assignment operator (??=), the assignment
can come after the inclusion, which avoids confusion and can lead to a more
natural recipe structure.
