Subject: [PATCH net 1/4] selftests/tc-testing: Fix Error: Specified qdisc kind is unknown.

All TEQL tests assume that sch_teql module is loaded. Load module in tdc.sh
before running qdisc tests.

Fixes following example error when running tests via tdc.sh for all TEQL
tests:

 # $ sudo ./tdc.py -d eth2 -e 84a0
 #  -- ns/SubPlugin.__init__
 # Test 84a0: Create TEQL with default setting
 # exit: 2
 # exit: 0
 # Error: Specified qdisc kind is unknown.
 #
 # -----> teardown stage *** Could not execute: "$TC qdisc del dev $DUMMY handle 1: root"
 #
 # -----> teardown stage *** Error message: "Error: Invalid handle.
 # "
 # returncode 2; expected [0]
 #
 # -----> teardown stage *** Aborting test run.

 # <_io.BufferedReader name=3> *** stdout ***
