Subject: [PATCH] dns-configuration: make dns_scope_free() static

systemd-resolved already has a dns_scope_free() function in
resolved-dns-scope.c for DnsScope. Since the one in dns-configuration.c
is only used internally, make it static.

This is necessary to allow systemd-resolved to be statically linked
with libsystemd-shared without symbol conflicts.
