tools lib traceevent: Add support for __print_hex()

Since the __print_hex() function is used in print fmt now, add
corresponding parser routines. This makes the output of perf script on
the kvm_emulate_insn event not to fail any more.

 before:
      kvm_emulate_insn:     [FAILED TO PARSE] rip=3238197797 ...

 after:
      kvm_emulate_insn:     0:c102fa25:89 10 (prot32)
