x86/vdso: Place vdso_data at beginning of vvar page
The offset of the vdso_data only has historic reasons, as back then
other vvars also existed and offset 0 was already used.
(See commit 8c49d9a74bac ("x86-64: Clean up vdso/kernel shared variables"))
Over time most other vvars got removed and offset 0 is free again.
Moving vdso_data to the beginning of the vvar page aligns x86 with other
architectures and opens up the way for the removal of the custom x86
vvar machinery.
