qscintilla: move to qt{5,6}Packages.nix

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 .
