fix(ttl): Compare SWB_UNIT1 in the second operand of the traffic branches

Rework the traffic blocks in A, B and C as explicit if/elseif branches
holding literal commands, and drop the derived swb_any/swb_opt from
config.ttl -- the branches read straight off the page and there is no
indirection to follow.

All nine conditions compared SWB_UNIT0 against itself, though:

    if     SWB_UNIT0 = 1 && SWB_UNIT0 = 1     ->  SWB_UNIT0 = 1
    elseif SWB_UNIT0 = 1 && SWB_UNIT0 = 0     ->  never
    elseif SWB_UNIT0 = 0 && SWB_UNIT0 = 1     ->  never

so the single-unit paths were unreachable. A DUT with only unit 0 would
have run the both-unit commands and hit bcmcmd on an absent unit 1,
while a DUT with only unit 1 fell through to the empty else and skipped
traffic entirely. Second operand is now SWB_UNIT1.

Verified per branch that the -u argument matches the condition guarding
it: both units carry no -u (tool default TL_UNITS="0 1"), unit-0-only
carries -u 0, unit-1-only carries -u 1, and the else stays empty.
