rubyspec/core/io/popen_spec: avoid lingering "ruby -e sleep" process
The ruby_cmd helper blindly escapes code blocks passed to it,
causing "sleep" to be quoted in the command-line. This quoting
results in IO.popen using a subshell (/bin/sh) to run the given
string command instead of invoking the Ruby executable directly.
Thus, IO.popen would only see the PID of the subshell via
IO#pid, and merely sending SIGKILL to the subshell would not
result in the child ("ruby -e sleep") being killed.
This problem with lingering ruby processes was easier to
reproduce on slow or heavily-loaded systems using low-scheduling
priority (e.g. "chrt -i 0 make test-rubyspec")
