x86/vdso: Only define map_vdso_randomized() if CONFIG_X86_64

Browse source 
... otherwise the compiler complains:

   arch/x86/entry/vdso/vma.c:252:12: warning: ‘map_vdso_randomized’ defined but not used [-Wunused-function]

But the #ifdeffery here is getting pretty ugly, so move around
vdso_addr() as well to cluster the dependencies a bit more.

It's still not particulary pretty though ...
