Test mpi/p4est_bug_01: remove test

This test needs an external p4est library built with debug symbols,
otherwise it "fails" because we do not error out while running the test
"expect=run".

Let's remove this test for now.

The long standing bug it documents is reported in
  https://github.com/dealii/dealii/issues/7428
