libdns: Avoid using compound literals (2).

* dirmngr/dns.h (dns_strsection1, dns_strsection3): Remove.
(dns_strclass1, dns_strclass3): Remove.
(dns_strtype1, dns_strtype3): Remove.
(dns_strsection, dns_strclass, dns_strtype): Directly use the
function.
* dirmngr/dns.c (dns_strsection): Use automatic variable.
(dns_strclass, dns_strtype): Likewise.
