[PATCH 3/3] credential-cache--daemon: change to the socket dir on startup

[Jeff King <peff@peff.net>]

From: Jon Griffiths <jon_p_griffiths@yahoo.com>

Changing to the socket path stops the daemon holding open
the directory the user was in when it was started,
preventing umount from working. We're already holding open a
socket in that directory, so there's no downside.

Thanks-to: Jeff King <peff@peff.net>
