rust: Remove the test cases whose parent dir is also present in the exclude list

rust: Remove the test cases whose parent dir is also present in the exclude list

To avoid overlap and redundancy of rust tests, remove the test cases whose
parent dir is already excluded.

Tests which are failing from below dirs are removed as these dirs are
already present in exclude list
            tests/run-make
            tests/rustdoc
            tests/mir-opt
            tests/ui-fulldeps
