Generalize timeout_scale

* test/lib/test/unit.rb (Test::Unit::TimeoutOption): renamed
  SubprocessOption.

* test/lib/test/unit.rb (Test::Unit::TimeoutOption#setup_options):
  prefer `--timeout-scale` option.

* test/lib/test/unit.rb (Test::Unit::TimeoutOption#non_options):
  prefer `ENV["RUBY_TEST_TIMEOUT_SCALE"]`.
