build: fix linking to libconfd

Commit fdbd8086b1e1 removed the explicit -lconfd flag from
lib_confd_la_LIBADD in favor of using the CONFD_LIBS variable. The
problem, however, is that ConfD doesn't use pkg-config nor anything
similar, so CONFD_LIBS is not created automatically by autotools.

Fix this problem by manually assigning -lconfd to the CONFD_LIBS
variable in the configure script.
