330: Fix: Haskell overlay r=blaggacao a=GTrunSec

using `lib.composeExtensions` for packageOverrides is more idiomatic.
Fixes: https://github.com/divnix/devos/pull/325#pullrequestreview-687772802
such as 
```
 python3 = pkgs.python3.override (old: {
   5 │ │ packageOverrides =
   4 │ │ │ pkgs.lib.composeExtensions
   3 │ │ │ │ (old.packageOverrides or (_: _: { }))
   2 │ │ │ │ packageOverrides;
   1 │ });
```
