parasite-vdso: vdso_map_compat under CONFIG_COMPAT

Browse source 
It's used in restorer to map compatible vDSO blob.
When !CONFIG_COMPAT it's not needed and even more:
vdso_fill_symtable_compat is macro and is undefined in that
case. It will never shoot, as compat_vdso is always false
for that case, but get rid of it.
  I also need to leave CONFIG_X86_64 here, as arch_prctl()
is not defined for x86_32.
