tools/power turbostat: Fix child's argument forwarding
[ Upstream commit 1da0daf746342dfdc114e4dc8fbf3ece28666d4f ]
Add '+' to optstring when early scanning for --no-msr and --no-perf.
It causes option processing to stop as soon as a nonoption argument is
encountered, effectively skipping child's arguments.
