Regression: cabal-3.12.1.0 install ignores --program-suffix when checking whether exe is already installed

[andreasabel]

cabal-3.12.1.0 install wrongly ignores --program-suffix when checking whether exe is already installed:

$ cabal-3.12.1.0 install hello
...
Symlinking 'hello' to '/Users/test/.local/bin/hello'

$ cabal-3.12.1.0 install hello --program-suffix=-new
...
Error: [Cabal-7149]
Path '/Users/test/.local/bin/hello' already exists. Use --overwrite-policy=always to overwrite.

cabal-3.10.3.0 can still do this correctly:

$ cabal-3.10.3.0 install hello --program-suffix=-new
...
Symlinking 'hello' to '/Users/test/.local/bin/hello-new'

Regression possibly introduced by:

• Fix --program-suffix resulting in invalid symlink #10056 ATTN: @wismill

The --program-suffix feature likely needs more systematic regression tests.
