  zshrc: add `NOETCHOSTS` parameter

`/etc/hosts` may be used as a denylist for undesired hosts on some systems.
In such usage scenarios the file may be large in size and parsing it may severely
impact shell startup time.

For example, on a system with `/etc/hosts` from https://github.com/StevenBlack/hosts:

```
% cat profile.zsh
#!/usr/bin/env zsh
zmodload zsh/zprof
source ./etc/zsh/zshrc
zprof
```

```
% ./profile.zsh | head -3
num  calls                time                       self            name
-----------------------------------------------------------------------------------

```

```
% NOETCHOSTS=1 ./profile.zsh | head -3
num  calls                time                       self            name
