perf trace beauty: Update the arch/x86/include/asm/irq_vectors.h copy with the kernel sources to pick POSTED_MSI_NOTIFICATION
To pick up the change in:
f5a3562ec9dd29e6 ("x86/irq: Reserve a per CPU IDT vector for posted MSIs")
That picks up this new vector:
$ cp arch/x86/include/asm/irq_vectors.h tools/perf/trace/beauty/arch/x86/include/asm/irq_vectors.h
$ tools/perf/trace/beauty/tracepoints/x86_irq_vectors.sh > after

static const char *x86_irq_vectors[] = {
[0x02] = "NMI",
[0x80] = "IA32_SYSCALL",
+ [0xeb] = "POSTED_MSI_NOTIFICATION",

Now those will be known when pretty printing the irq_vectors:*
tracepoints.
