perf tools intel-pt-decoder: Update insn.h from the kernel sources

To pick up the changes in:

  ee6a7354 ("kprobes/x86: Prohibit probing on exception masking instructions")

That doesn't entail changes in tooling, but silences this perf build
warning:

  Warning: Intel PT: x86 instruction decoder header at 'tools/perf/util/intel-pt-decoder/insn.h' differs from latest version at 'arch/x86/include/asm/insn.h'
