Subject: [PATCH] Relocate tools on Flatcar in BPF mode

In https://github.com/falcosecurity/falco/pull/2043 we've added logic
for relocating tools on Flatcar when running falco-driver-loader in kmod
mode. This logic is relevant for BPF mode, too, which is currently
broken on Flatcar. Call flatcar_relocate_tools in BPF mode, too.
