    selftests/tc-testing: Fix Error: Specified qdisc kind is unknown.
    
    [ Upstream commit aef6e908b54200d04f2d77dab31509fcff2e60ae ]
    
    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.
     #
