tests: Fix linking of utility programs

The GNU linker used to link against all libraries that were
specified on the command line. Since libkdumpfile also drags in
libaddrxlat, linking with libkdumpfile always worked. This
behaviour changed at some point, and now libraries are linked only
if a library symbol is actually needed. These utilities do not use
anything from libkdumpfile, so this object is removed from the
list, and then linking fails.

This fixes issue #30.
