objtool, kprobes/x86: Sync the latest <asm/insn.h> header with tools/objtool/arch/x86/include/asm/insn.h

The following commit:

  ee6a7354a362: kprobes/x86: Prohibit probing on exception masking instructions

Modified <asm/insn.h>, adding the insn_masking_exception() function.

Sync the tooling version of the header to it, to fix this warning:

  Warning: synced file at 'tools/objtool/arch/x86/include/asm/insn.h' differs from latest kernel version at 'arch/x86/include/asm/insn.h'
