patch 9.0.1966: configure prints stray 6 when checking libruby
Problem: configure prints stray 6 when checking libruby
Solution: redirect stdout to dev/null
configure: Do not print "6" when checking for libruby
`expr` will print the matched string length to the standard output.
Current `configure` output looks like this:
```
checking Ruby header files... /usr/include/ruby-3.1.0
6
```
The script really only cares about `expr` exit code.
closes: #13234
