perf tools: Sync copy of syscall_64.tbl with the kernel
Noticed by the build system, that emitted this warning:
Warning: x86_64's syscall_64.tbl differs from kernel
This was due to the wiring up of the recently added preadv2 & pwritev2 syscalls to the compat code, which hadn't been done by the patch introducing those syscalls: 4babf2c5efb7 ("x86: wire up preadv2 and pwritev2").
The patch doing the compat wiring was:
482dd2ef1244 ("x86/syscalls: Wire up compat readv2/writev2 syscalls")
This just silences the perf build warning, as compat syscalls still can't be supported in 'perf trace´ due to limitations in the raw_syscalls:sys_{enter,exit} tracepoints it relies on.
