aef6e908b5 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 *** Aborting test run.

db925bca33 selftests/tc-testing: Fix cannot create /sys/bus/netdevsim/new_device: Directory nonexistent 
Install netdevsim to provide /sys/bus/netdevsim/new_device interface.

It helps to fix:

2b9843fbe1 tc-testing: Add tdc to kselftests 
Add tdc to existing kselftest infrastructure so that it can be run with
existing kselftests. TDC now generates objects in objdir/kselftest
without cluttering main objdir, leaves source directory clean, and
installs correctly in kselftest_install, properly adding itself to
run_kselftest.sh script.

Add tc-testing as a target of selftests/Makefile. Create tdc.sh to run
tdc.py targets with correct arguments. To support single target from
selftest/Makefile, combine tc-testing/bpf/Makefile and
tc-testing/Makefile. Move action.c up a directory to tc-testing/.

Tested with:
 make O=/tmp/{objdir} TARGETS="tc-testing" kselftest
 cd /tmp/{objdir}
 cd kselftest
 cd tc-testing
 ./tdc.sh

 make -C tools/testing/selftests/ TARGETS=tc-testing run_tests

 make TARGETS="tc-testing" kselftest
 cd tools/testing/selftests
 ./kselftest_install.sh /tmp/exampledir
 My VM doesn't run all the kselftests so I commented out all except my
 target and net/pmtu.sh then:
 cd /tmp/exampledir && ./run_kselftest.sh
