tools headers: Sync linux/socket.h with kernel sources

Browse Source 
To pick up changes from:

  d73c167708 ("socket: Split out a getsockname helper for io_uring")
  4677e78800 ("socket: Unify getsockname and getpeername implementation")
  bf33247a90 ("net: Add struct sockaddr_unsized for sockaddr of unknown length")

This should be used to beautify socket syscall arguments and it addresses
these tools/perf build warnings:

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

Please see tools/include/uapi/README.
