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

To pick the changes in:

  b848b26c6672c9b9 ("net: Kill MSG_SENDPAGE_NOTLAST")
  5e2ff6704a275be0 ("scm: add SO_PASSPIDFD and SCM_PIDFD")
  4fe38acdac8a71f7 ("net: Block MSG_SENDPAGE_* from being passed to sendmsg() by userspace")
  b841b901c452d926 ("net: Declare MSG_SPLICE_PAGES internal sendmsg() flag")

That don't result in any changes in the tables generated from that
header.

But while updating I noticed we were not handling MSG_BATCH and MSG_ZEROCOPY in the
hard coded table for the msg flags table, add them.

This silences this perf build warning:

  Warning: Kernel ABI header differences:
