build: fix linking libqemutestdriver with LTO enabled

openSUSE Factory is in the process of enabling Link Time Optimization [0]
and stumbled upon missing symbols when linking libqemutestdriver

libtool: link: gcc -shared  -fPIC -DPIC  ../src/libvirt_qemu_probes.o  \
-Wl,--whole-archive ../src/.libs/libvirt_driver_qemu_impl.a \
../src/.libs/libvirt_driver_network_impl.a \
../src/.libs/libvirt_driver_storage_impl.a -Wl,--no-whole-archive  \
-lcap-ng -lgnutls -lnl-route-3 -lnl-3 -ldbus-1 -lselinux -lapparmor \
/usr/lib/libxml2.so -ldl -lz -llzma -lm -lblkid -ltirpc  \
-fstack-protector-strong -O2 -fstack-protector-strong -flto=16 -g -O2 \
-fstack-protector-strong -flto=16 -g \
-Wl,-soname -Wl,libqemutestdriver.so -o .libs/libqemutestdriver.so
...

The missing symbols are provided by GNUlib. Add it when linking
libqemutestdriver.
