tools include UAPI: Sync x86's syscalls_64.tbl and generic unistd.h to pick up
clone3 and pidfd_open
05a70a8ec287 ("unistd: protect clone3 via __ARCH_WANT_SYS_CLONE3")
8f3220a80654 ("arch: wire-up clone3() syscall")
7615d9e1780e ("arch: wire-up pidfd_open()")
Silencing the following tools/perf build warnings
Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/unistd.h'
differs from latest version at 'include/uapi/asm-generic/unistd.h'
diff -u tools/include/uapi/asm-generic/unistd.h

Warning: Kernel ABI header at
'tools/perf/arch/x86/entry/syscalls/syscall_64.tbl' differs from latest version
at 'arch/x86/entry/syscalls/syscall_64.tbl'
diff -u tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
arch/x86/entry/syscalls/syscall_64.tbl
Now 'perf trace -e pidfd*,clone*' will trace those syscalls as well as the
others with those prefixes.
