libbeauty: Hook up the x86 irq_vectors table generator

I.e. after running:

  $ make -C tools/perf O=/tmp/build/perf

We end up with:

  $ cat /tmp/build/perf/trace/beauty/generated/x86_arch_irq_vectors_array.c
  static const char *x86_irq_vectors[] = {
  	[0x02] = "NMI",
  	[0x12] = "MCE",
  	[0x20] = "IRQ_MOVE_CLEANUP",
  	[0x80] = "IA32_SYSCALL",
  	[0xec] = "LOCAL_TIMER",
  	[0xed] = "HYPERV_STIMER0",
  	[0xee] = "HYPERV_REENLIGHTENMENT",
  	[0xef] = "MANAGED_IRQ_SHUTDOWN",
  	[0xf0] = "POSTED_INTR_NESTED",
  	[0xf1] = "POSTED_INTR_WAKEUP",
  	[0xf2] = "POSTED_INTR",
  	[0xf3] = "HYPERVISOR_CALLBACK",
  	[0xf4] = "DEFERRED_ERROR",
  	[0xf6] = "IRQ_WORK",
  	[0xf7] = "X86_PLATFORM_IPI",
  	[0xf8] = "REBOOT",
  	[0xf9] = "THRESHOLD_APIC",
  	[0xfa] = "THERMAL_APIC",
  	[0xfb] = "CALL_FUNCTION_SINGLE",
  	[0xfc] = "CALL_FUNCTION",
  	[0xfd] = "RESCHEDULE",
  	[0xfe] = "ERROR_APIC",
  	[0xff] = "SPURIOUS_APIC",
  };
  $

Now its just a matter of using it, associating it to tracepoint arguments named
'vector', all of which can be correctly used with this table, for int args.

At some point we should move tools/perf/trace/beauty to tools/beauty/,
so that it can be used more generally and even made available externally
like libbpf, libperf, libtraceevent, etc.
