bpf: Conditionally include dynptr copy kfuncs
Since commit a498ee7576de ("bpf: Implement dynptr copy kfuncs"), if
CONFIG_BPF_EVENTS is not enabled, but BPF_SYSCALL and DEBUG_INFO_BTF are,
the build will break like so:
BTFIDS vmlinux.unstripped
WARN: resolve_btfids: unresolved symbol bpf_probe_read_user_str_dynptr
WARN: resolve_btfids: unresolved symbol bpf_probe_read_user_dynptr
WARN: resolve_btfids: unresolved symbol bpf_probe_read_kernel_str_dynptr
WARN: resolve_btfids: unresolved symbol bpf_probe_read_kernel_dynptr
WARN: resolve_btfids: unresolved symbol bpf_copy_from_user_task_str_dynptr
WARN: resolve_btfids: unresolved symbol bpf_copy_from_user_task_dynptr
WARN: resolve_btfids: unresolved symbol bpf_copy_from_user_str_dynptr
WARN: resolve_btfids: unresolved symbol bpf_copy_from_user_dynptr
make[2]: *** [scripts/Makefile.vmlinux:72: vmlinux.unstripped] Error 255
make[2]: *** Deleting file 'vmlinux.unstripped'
make[1]: *** [/repo/malin/upstream/linux/Makefile:1242: vmlinux] Error 2
make: *** [Makefile:248: __sub-make] Error 2
Guard these symbols with #ifdef CONFIG_BPF_EVENTS to resolve the problem.
Fixes: a498ee7576de ("bpf: Implement dynptr copy kfuncs")
