just a test branch for getting ios working with fork of substrate

[4meta5]

fork of substrate info

Here is the fork, right on top of v2.0.0-rc4 tag so that there aren't version problems involving master vs substrate-subxt: https://github.com/4meta5/substrate/tree/ios-ignore-sysinfo

what did I change? see the last three commits on that branch, I ignored "ios" for sysinfo and netstat in the Cargo.toml and the metrics.rs file.

this branch and the current error

I'm referencing the fork in the patches.crates-io of the Cargo.toml and it is still returning this error when I run cargo make ios in the root

This branch isn't intended to be merged. It's intended to get compilation on ios using a fork of substrate so I can justifying PRing with the changes.
