Remove backtrace dep from anyhow in features status dump tool

According to `anyhow`'s Cargo.toml:

> On compilers older than 1.65, features=["backtrace"] may be used to enable
> backtraces via the `backtrace` crate. This feature has no effect on 1.65+
> besides bringing in an unused dependency, as `std::backtrace` is always
> preferred.

So this is just bringing in an unused dependency.
