selftests: tc-testing: use $IP in hfsc test 8c39 setup

Browse Source 
Test 8c39 brings up lo with a bare "ip" command. nsPlugin runs it as
"$IP netns exec <ns> ip ...", and as tdc runs commands with an empty
environment, "ip netns exec" searches only the default execvp() path
(/bin:/usr/bin). On systems that install ip only in /sbin, like Fedora,
the setup fails:

  # ./tdc.py -e 8c39
  Test 8c39: HFSC classify walk still reaches leaf after lateral drift
  -----> prepare stage *** Could not execute: "ip link set lo up"
  -----> prepare stage *** Error message: "exec of "ip" failed: No such file or directory

Use $IP like all other tdc tests do.

Fixes: 1e24c4f2ee ("selftests: tc-testing: add a lateral-drift hfsc classify-walk test")
