Fix link errors in tools/nss and tests

Although a simple 'make' of libvirt.git works, building libvirt 4.6.0
with 'osc build ...' fails in tools/nss and tests, with output along
the lines of:

[  469s] libtool: link: gcc -shared  -fPIC -DPIC  -Wl,--whole-archive nss/.libs/libnss_libvirt_impl.a -Wl,--no-whole-archive  -lpthread -lutil -ltirpc  -fstack-protector-strong -grecord-gcc-switches -O2 -fstack-protector-strong -g -Wl,--version-script=./nss/libvirt_nss.syms -Wl,-z -Wl,relro -Wl,-z -Wl,now -Wl,--no-copy-dt-needed-entries -Wl,-z -Wl,defs -grecord-gcc-switches -O2 -fstack-protector-strong -g   -pthread -Wl,-soname -Wl,libnss_libvirt.so.2 -o nss/.libs/libnss_libvirt.so.2
[  469s] nss/.libs/libnss_libvirt_impl.a(libvirt_nss_la-virjsoncompat.o): In function `virJSONJanssonOnce':
[  469s] /home/abuild/rpmbuild/BUILD/libvirt-4.6.0/src/util/virjsoncompat.c:63: undefined reference to `dlopen'
[  469s] /home/abuild/rpmbuild/BUILD/libvirt-4.6.0/src/util/virjsoncompat.c:79: undefined reference to `dlsym'
...

A quick hack is to add '-ldl' to the linker flags for libnss_libvirt_impl
and /libnss_libvirt_guest_impl. Will ask about a proper fix on libvirt
dev list.
