tcp_splice, udp_flow: fcntl64() support on PPC64 depends on glibc version

Browse source 
I explicitly added fcntl64() to the list of allowed system calls for
PPC64 a while ago, and now it turns out it's not available in recent
Debian builds. The warning from seccomp.sh is harmless because we
unconditionally try to enable fcntl() anyway, but take care of it
anyway.
