haskell.compiler.ghc92*: backport Cabal bugfix for Paths_ modules

Browse source 
There is a code generation bug in Cabal-3.6.3.0. For packages configured with
--enable-relocatable, Cabal would generate code that doesn't compile.

There isn't an upstream issue, but the issue is described in the commit that
fixed it:
6c796218c9

It was fixed in Cabal-3.8.*
Backport the fix to the Cabal library that ships with ghc-9.2.4

Co-authored-by: sternenseemann <sternenseemann@systemli.org>

Closes #200063.
