contrib/git-credential-gnome-keyring.c: support really ancient gnome-keyring 

The gnome-keyring lib (0.4) distributed with RHEL 4.X is really ancient
and does not provide most of the synchronous functions that even ancient
releases do.  Thankfully, we're only using one function that is missing.
Let's emulate gnome_keyring_item_delete_sync() by calling the asynchronous
function and then triggering the event loop processing until our
callback is called.
