x86/vdso: Access rng data from kernel without vvar

Browse source

Remove the usage of the vvar _vdso_rng_data from the kernel-space code,
as the x86 vvar machinery is about to be removed.
The definition of the structure is unnecessary, as the data lives in a
page pre-allocated by the linker anyways.
The vdso user-space access to the rng data will be switched soon.

DEFINE_VVAR_SINGLE() is now unused. It will be removed later togehter
with the rest of vvar.h.
