rcutorture/kvm.sh: Use consistent help text for --qemu-args

The '--qemu-args' option's help text is wrongly copied from '--qemu-cmd'
option and its argument type description message format is inconsistent
with other arguments.  This commit fixes the usage and type messages to
be consistent with others.
