mvnix-update uses .override which blocks the use of callPackage

[FRidh]

Consider the file builder.nix

{ mavenix, ... }:

mavenix.buildMaven {
...
}

and

{
  foo = callPackage ./builder { };
}

Using mvnix-update -E "(import ./.).foo" will fail because .override is redefined by callPackage. This is a common issue, and can be worked around by the user, however, I think it would be better if buildMaven defines an overrideAttrs instead.

For Python I introduced at the time overridePythonAttrs, but in retrospect I think all specific builders should re-define overrideAttrs. See also NixOS/nixpkgs#46842 (comment).

Something like this #19?

This has been fixed.
