fix(iroh-net): unexpected cfg condition values / possible fix on netbsd (#2476)

## Description

We had some CLI tests that had `#[cfg(feature = "fs-store")]`, but that
feature doesn't exist in `iroh-cli`... so they were never compiled (and
some related code needed for these tests was deleted. I reintroduced
it).

This also fixes what is likely a bug, where `#[cfg(target_arch =
"netbsd")]` was used, but there is no "architecture" netbsd. Only an
*OS* netbsd.
