signal: unify compat_siginfo_t

Browse Source 
--EWB Added #ifdef CONFIG_X86_X32_ABI to arch/x86/kernel/signal_compat.c
      Changed #ifdef CONFIG_X86_X32 to #ifdef CONFIG_X86_X32_ABI in
      linux/compat.h

      CONFIG_X86_X32 is set when the user requests X32 support.

      CONFIG_X86_X32_ABI is set when the user requests X32 support
      and the tool-chain has X32 allowing X32 support to be built.
