test: reduce unnecessary output

* lib/test/unit.rb (Test::Unit::Runner#del_status_line): update
  @status_line_size and return true value.

* lib/test/unit.rb (Test::Unit::Runner#{put,add,jobs}_status): return
  non-nil/false if status line is used.

* lib/test/unit.rb (Test::Unit::Runner#_run_parallel): clear status
  line at last.
