llvm::BTFDebug crashes on some data types

[riptl]

Reported by @alessandrod
Caused by #32

Problem

The BTF (BPF Type Format) debug info format does not support non-kernel data types like complex numbers.
This breaks compilation of some Rust and C programs.

Suggested Fix

Remove BTF debug info for arch sbf and sbfv2.
There is currently no need for BTF debug syms because we have DWARF support.
