ebpf: Updated eBPF program and skeleton.
Updated section name, so libbpf should init/gues proper program type without specifications during open/load. Also, added map_flags with explicitly declared BPF_F_MMAPABLE. Added check for BPF_F_MMAPABLE flag to meson script and requirements to libbpf version. Also changed fragmentation flag check - some TCP/UDP packets may be considered fragmented if DF flag is set.
