perf beauty: Update copy of linux/socket.h with the kernel sources

To pick the changes in:

Fixes: d32f89da7fa8ccc8 ("net: add accept helper not installing fd")
Fixes: bc49d8169aa72295 ("mctp: Add MCTP base")

This automagically adds support for the AF_MCTP protocol domain:

  $ tools/perf/trace/beauty/socket.sh > before
  $ cp include/linux/socket.h tools/perf/trace/beauty/include/linux/socket.h
  $ tools/perf/trace/beauty/socket.sh > after
  $ diff -u before after

   	[43] = "SMC",
   	[44] = "XDP",

  $

This will allow 'perf trace' to translate 45 into "MCTP" as is done with
the other domains:

  # perf trace -e socket*
     0.000 chronyd/1029 socket(family: INET, type: DGRAM|CLOEXEC|NONBLOCK, protocol: IP) = 4
  ^C#

This addresses this perf build warning:

  Warning: Kernel ABI header at 'tools/perf/trace/beauty/include/linux/socket.h' differs from latest version at 'include/linux/socket.h'
