removed old HOL4 import -- corresponding exporter is lost, code is broken, no users known, maintenance nightmare

(*  Title:      HOL/TPTP/TPTP_Parser_Test.thy
    Author:     Nik Sultana, Cambridge University Computer Laboratory

Some tests for the TPTP interface. Some of the tests rely on the Isabelle
environment variable TPTP_PROBLEMS_PATH, which should point to the
TPTP-vX.Y.Z/Problems directory.
