test/ruby/test_thread.rb (test_fork_while_parent_locked): reduce threads

Browse source 
Reduce thread counts unconditionally for some CI systems with
low limits..  And Solaris apparently lacks RLIMIT_NPROC, so we
can't detect resource limits and scale the test appropriately.

[ruby-core:90670] [Bug #15430]
