[PATCHv7 11/18] x86/vdso: Undefine CONFIG_HUGETLB_PAGE_OPTIMIZE_VMEMMAP for vdso32

[Kiryl Shutsemau (Meta)]

The 32-bit VDSO build on x86_64 uses fake_32bit_build.h to undefine
various kernel configuration options that are not suitable for the
VDSO context or may cause build issues when including kernel headers.

Undefine CONFIG_HUGETLB_PAGE_OPTIMIZE_VMEMMAP in fake_32bit_build.h to
prepare for change in  HugeTLB Vmemmap Optimization.
