feat(ttl): Drive traffic and port wait from SWB_UNIT0/SWB_UNIT1

Browse Source 
The bench is not always fully populated. config.ttl now declares which
switch units exist:

    SWB_UNIT0 = 1   ; this DUT has switch unit 0
    SWB_UNIT1 = 1   ; this DUT has switch unit 1

Two values are derived there rather than repeating the same test in
three scripts: swb_any (0 = no unit at all) and swb_opt, the suffix
appended to each blanton_traffic_linespeed call -- "" for both units so
the tool's own TL_UNITS="0 1" applies, " -u 0" or " -u 1" for a single
one.

Script A, B and C build their traffic commands with sprintf2 and the
suffix, wrapped in `if swb_any = 1`. A half-populated DUT no longer
issues bcmcmd against an absent unit, and a DUT with no switch board
skips the traffic stage outright instead of filling the log with
failures.

wait_init.ttl reads the same two flags instead of its own copies, so the
wait and the traffic blocks cannot disagree about what is installed.

Script A -> V1.0.5.
