Thomas Huth a0d6d7454a tests/hd-geo-test: Skip test when images can not be created 
In certain environments like restricted containers, we can not create
huge test images. To be able to use "make check" in such container
environments, too, let's skip the hd-geo-test instead of failing when
the test images could not be created.
