[CRIU] [PATCHv2 4/9] compat/x86/vdso: add 32-bit vdso symbols to array

[Dmitry Safonov]

32-bit vDSO blob contains additional symbols on x86.
I wanted to add it under ifdefs (CONFIG_X86_{64,32}), but
it looks like, we need to keep VDSO_SYMBOL_MAX the same
and the additional cost is just a little bit larger
rt symtab massive.
