tool/runruby.rb: test with smallest possible machine stack
Lets ensure none of our C functions use too much stack space and
fix all excessive stack usage before releasing the next version.
Reducing C stack usage should reduce conservative GC scanning
time and improve performance.
If there are platform-dependent test failures; excessive stack
usage should be fixed; rather than increasing minimum values or
removing these envs from testing.
* tool/runruby.rb: use smallest possible machine stack size
[ruby-core:81597] [Feature #13637]
