Make HKP keyserver engine work again.

We had some debug code here which prevented it from working.
The host selection code still needs a review!

	* ks-engine-http.c (ks_http_help): Do not print help for hkp.
	* ks-engine-hkp.c (ks_hkp_help): Print help only for hkp.
	(send_request): Remove test code.
	(map_host): Use xtrymalloc.

	* certcache.c (classify_pattern): Remove unused variable and make
	explicit substring search work.
