git-completion.zsh: define __gitcomp_file compatibility function

Commit fea16b47b60 (Fri Jan 11 19:48:43 2013, Manlio Perillo,
git-completion.bash: add support for path completion), introduced a new
__gitcomp_file function that uses the bash builtin "compgen". The
function was redefined for ZSH in the deprecated section of
git-completion.bash, but not in the new git-completion.zsh script.

As a result, users of git-completion.zsh trying to complete "git add
fo<tab>" get an error:

git add fo__gitcomp_file:8: command not found: compgen

This patch adds the redefinition and removes the error.
