run-tests: give each child its own tmp dir (issue1911) Fixes bug introduced by f8b4df4b033d (issue1911: --tmpdir plus parallel mode = fail), and also fixes the long-standing quirk that parallel mode created multiple /tmp/hgtests.XXXXXX directories. Now there is only one /tmp/hgtests.XXXXXX, with child0, child1, etc. under it.
