Support for not using realpath

[kwasimensah]

https://github.com/sindresorhus/resolve-from/blob/main/index.js#L16 unconditionally uses realpathSync which is a problem in contexts where we don't want to give lstat permissisons to every directory in the hierarchy (sandboxes for example). Node's --preserve-symlinks --preserve-symlinks-main options let you work around this.

I'm running into this because this is how eslint loads it's configuration (through import-fresh). Happy to take a stab at this if this something you want to support in this project.
