Since it is a somewhat common library, with support for multiple qt
versions, it is safer to put each version of it in libsForQt5 and
qt6Packages attribute sets. Also, it is cleaner to put the darwin
if-else inside the expression, in relation to https://github.com/NixOS/rfcs/pull/140 .

Given the number of entries in TCLLIBPATH when using tcllib, this
results in some massive startup time speedups:
```
$ nix shell 'nixpkgs#tcl2048' -c sh -c 'echo q | time 2048'
```
takes .44s on master but only .01s with this change.
