x86/vdso: Replace hex int80 CFI annotations with GAS directives

Maintaining the current CFI annotations written in R'lyehian is
difficult for most of us.  Translate them to something a little
closer to English.

This will remove the CFI data for kernels built with extremely
old versions of binutils.  I think this is a fair tradeoff for
the ability for mortals to edit the asm.
