Do not rely on symlinks when openning a library

The symlink libopenscap_sce.so is supposed to be consumed
by linker, but not by a run-time. The symlink is not assured
to point-out to the latest shared object (otherwise libtool
authors would not introduced such symlink).

This fix should enable use of SCE without openscap-engine-sce-devel
package installed.
