hadrian: Also produce versioned wrapper scripts
Since !6133 (closed) we are more consistent about producing versioned executables but we still didn't produce versioned wrappers. This patch adds the corresponding versioned wrappers to match the versioned executables in the relocatable bindist.
I also fixed the ghci wrapper so that it wasn't overwritten during installation.
The final bindir looks like:
