scripts/faddr2line: Don't filter out non-function symbols from readelf
As Josh points out in 20230724234734.zy67gm674vl3p3wv@treble:
> Problem is, I think the kernel's symbol printing code prints the
> nearest kallsyms symbol, and there are some valid non-FUNC code
> symbols. For example, syscall_return_via_sysret.
so we shouldn't be considering only 'FUNC'-type symbols in the output
from readelf.
Drop the function symbol type filtering from the faddr2line outer loop.
