[PATCH 4/9] rcutorture/kvm.sh: Use consistent usage for --qemu-args

[SeongJae Park]

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

Fixes: e9ce640001c6 ("rcutorture: Add --qemu-args argument to kvm.sh")
