Subject: [PATCH] try to show timeout sec

http://ci.rvm.jp/results/trunk-gc-asserts@ruby-sp2-noble-docker/5632508
```
  1) Error:
TestEval#test_outer_local_variable_under_gc_compact_stress:
Test::Unit::ProxyError: execution of Test::Unit::CoreAssertions#assert_separately expired timeout (10 sec)
pid 1339179 killed by SIGABRT (signal 6) (core dumped)
```

seems that timeout scale doesn't work even though `RUBY_TEST_TIMEOUT_SCALE`
is specified.

This patch tries to print the timeout with scale information.
