In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.
```

I'm not going anywhere, I'm focusing my energy on other issues, and
getting pinged as a maintainer for packages is a bit distracting (also
I'm not using most of these packages anyways!)
Includes LC_ALL = "en_US.UTF-8"; that resolves a locale.Error exception
during the check phase.
