Title: Proposed fix for bug #1327: don't remove DNS entries that are in use

Bug report: https://sourceforge.net/p/curl/bugs/1327/

hostcache_timestamp_remove() should remove old *unused* entries from the host cache, but it never checked whether the entry was actually in use. This complements commit 030a2b8cb.
