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)
