x86/vdso: Remove #ifdeffery around page setup variants

Browse source

Replace the open-coded ifdefs in C sources files with IS_ENABLED().
This makes the code easier to read and enables the compiler to typecheck
also the disabled parts, before optimizing them away.
To make this work, also remove the ifdefs from declarations of used
variables.
