runtime/pprof: TestLabelSystemstack parallelLabelHog.func1 must be labeled

Browse Source 
The closure in parallelLabelHog should be labeled in a addition to
parallelLabelHog itself. Generally samples on that goroutine land on
labelHog, but there is a small portion of the closure outside of
labelHog.

Fixes #50740.
