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

To pick up the fixes in:

  0645fbe ("net: have do_accept() take a struct proto_accept_arg argument")

That just changes a function prototype, not touching things used by the
perf scrape scripts such as:

  $ tools/perf/trace/beauty/sockaddr.sh | head -5
  static const char *socket_families[] = {
  	[0] = "UNSPEC",
  	[1] = "LOCAL",
  	[2] = "INET",
  	[3] = "AX25",
  $

This addresses this perf tools build warning:

  Warning: Kernel ABI header differences:
    diff -u tools/perf/trace/beauty/include/linux/socket.h include/linux/socket.h
