dirmngr: Load the hosts file into libdns.

Browse Source 
* dirmngr/dns-stuff.c (libdns_init): Actually load the hosts file into
libdns.
--

Previously, connecting to key servers specified in /etc/hosts was not
possible because libdns' hosts structure was initialized, but not
filled with the content of the hosts file.
