x86 vDSO: new layout

Browse source

This revamps the vDSO linker script to lay things out with the best
packing of the data and good, separate alignment of the code.  The
rigid layout using VDSO_TEXT_OFFSET no longer matters to the kernel.
I've moved the layout parts of the linker script into a new include
file, vdso-layout.lds.S; this is in preparation for sharing the script
for the 32-bit vDSO builds too.
