[bug#66562] [PATCH] gnu: emacs-haskell-snippets: Fix haskell-snippets-dir value.

[Rostislav Svoboda]

* gnu/packages/emacs-xyz.scm (emacs-haskell-snippets): Fix
haskell-snippets-dir value

The value of haskell-snippets-dir was:
  
/gnu/store/*-emacs-haskell-snippets-*/share/emacs/site-lisp/haskell-snippets-*/
It needs to be:
  /gnu/store/*-emacs-haskell-snippets-*/share/emacs/site-lisp/

The error was (abbreviated):
No such file or directory, 
/gnu/store/*-emacs-haskell-snippets-*/share/emacs/site-lisp/haskell-snippets-*/snippets
