bpf: disable hardening in favor of unwinding

I had missed that once hardening is enabled, it automatically disables
any exposure of JITed addresses, therefore when crashes or warnings are
thrown we don't unwind beyond a helper function. For now disable hardening.

After merge window I'll see if it's possible to detangle the case where
kernel queries kallsyms internally to find function names whenever a WARN
or BUG is thrown. If that's not possible easily, we can potentially add a
harden mode 3 which does hardening but does not disable kallsyms exposure
and then set this here for tools like syzkaller.
