tools headers: Update x86's syscall_64.tbl and uapi/asm-generic/unistd

To pick up the changes introduced in the following csets:

  2b188cc1bb85 ("Add io_uring IO interface")
  edafccee56ff ("io_uring: add support for pre-mapped user IO buffers")
  3eb39f47934f ("signal: add pidfd_send_signal() syscall")

This makes 'perf trace' to become aware of these new syscalls, so that
one can use them like 'perf trace -e ui_uring*,*signal' to do a system
wide strace-like session looking at those syscalls, for instance.

For example:

  # perf trace -s io_uring-cp ~acme/isos/RHEL-x86_64-dvd1.iso ~/bla

More work needed to make the tools/perf/examples/bpf/augmented_raw_syscalls.c
BPF program to copy the 'struct io_uring_params' arguments to perf's ring
buffer so that 'perf trace' can use the BTF info put in place by pahole's
conversion of the kernel DWARF and then auto-beautify those arguments.

This patch produces the expected change in the generated syscalls table
for x86_64:

This silences these perf build warnings:
