test-tool run-command: fix flip-flop init pattern

In be5d88e1128 (test-tool run-command: learn to run (parts of) the
testsuite, 2019-10-04) an init pattern was added that would use
TESTSUITE_INIT, but then promptly memset() everything back to 0. We'd
then set the "dup" on the two string lists.

Our setting of "next" to "-1" thus did nothing, we'd reset it to "0"
before using it. Let's set it to "0" instead, and trust the
"STRING_LIST_INIT_DUP" to set "strdup_strings" appropriately for us.

Note that while we compile this code, there's no in-tree user for the
"testsuite" target being modified here anymore, see the discussion at
and around <nycvar.QRO.7.76.6.2109091323150.59@tvgsbejvaqbjf.bet>[1].
