Update expected stderr.txt for tests/examples/find-global-state

Under gcc 6 we get two notes emitted for line 41 column 5; enabling
caret-printing shows they're at:

tests/examples/find-global-state/input.c:41:5: note: use of global state "int q" here
   q += p;
     ^~
tests/examples/find-global-state/input.c:41:5: note: use of global state "int q" here
   q += p;
   ~~^~~~
