Revert "Make GOMAXPROCS CPU limit aware"

I shouldn't have merged this without running the tests.

This libray logs to stderr on init, which is a no go for us.

Re. test failure:

```
[stderr]
2023/05/17 18:21:04 maxprocs: Leaving GOMAXPROCS=2: CPU quota undefined
```
This reverts commit 59050f97f637b7cb423e6f5b63e36c1ea973c183.
