recipes-archive-melpa: fix incorrect source hashes

This is basically NixOS/nixpkgs#309270 with
two fixes excluded.

The fix for smartparens is excluded because it has already been
fixed[1] here.

The fix for flycheck-cfn is also excluded because it has been bumped
to 20240512.2341 in 4fe6cc3.
However, the new hash is still incorrect.  Its fix is in the next
commit.
