x86: vdso put vars in rodata
This adds a const to the definitions vvar.c makes, so that the vdso_*
variables go into .rodata instead of .data. This is essentially a
cosmetic change, just giving the section headers in the vDSO file more
pleasing flags. These variables are read-only from the perspective of
the vDSO itself and user mode, even though the contents of the DSO image
were adjusted at boot.
