pypy27Packages.pluthon: fix eval

[trofi]

Without the change the eval fails to concatenate lists as:

$ nix build --no-link -f. pypy27Packages.pluthon
error:
   … while evaluating the attribute 'drvPath'
     at lib/customisation.nix:365:7:
      364|     in commonAttrs // {
      365|       drvPath = assert condition; drv.drvPath;
         |       ^
      366|       outPath = assert condition; drv.outPath;
