multilib_global: Fix KERNEL_VERSION expansion problems

KERNEL_VERSION gets expanded at runtime to contain the real kernel
version. There is code to ensure the signatures are determinisic but
the multilib expansion code breaks this.

Exclude the variable from the datastore used for expansion to avoid this.
