rpmSetTables() call in rpmbuild has been dying long enough by now

- The call to rpmSetTables() from rpmbuild is simply redundant for
  all I can tell, it gets called from inside rpmrc/config processing
  with the same values and the extra call here never changes anything
  as the tables have already been set through rpmReadConfigFiles()
  whether building for several targets or not.
