LU-9327 test: handle nodes lacking numbers in names for hostlist_expand.

Currently hostlist_expand() in test-framework assumes all node names will
contain numbers to sort them by. It is possible to have nodes that instead
are named alphabetical in nature (nodea, nodeb, ...). Handle this additional
case.
