[cargo-gnaw] Tweak tests to fix cargo roll

In rust-lang/cargo#10243, cargo was changed to
disallow crate-types that produce the same filename. This can happen
with `lib` and `rlib`, or `dylib` and `cdylib`. This changes the
`multiple_crate_type` to split out these into multiple sub-crates.

Note that because cargo-gnaw currently only supports generating rules
for `lib` types, we don't produce anything for the
`sub-crate-with-rlib`.
