Randy Dunlap 7c0afcad75 bpf: BPF_PRELOAD depends on BPF_SYSCALL
Fix build error when BPF_SYSCALL is not set/enabled but BPF_PRELOAD is
by making BPF_PRELOAD depend on BPF_SYSCALL.

ERROR: modpost: "bpf_preload_ops" [kernel/bpf/preload/bpf_preload.ko] undefined!

This builds kernel module with several embedded BPF programs that are
pinned into BPF FS mount point as human readable files that are
useful in debugging and introspection of BPF programs and maps.
