container/heap: call t.Helper() in verify()

I modified verify() to fail every time to test the change. Before adding
t.Helper() (line 37 is in verify()):
/.../go/src/container/heap/heap_test.go:37: forced failure
FAIL

Afer adding t.Helper() (line 67 is where verify() is called):
/.../go/src/container/heap/heap_test.go:67: forced failure
FAIL

Fixes #21863
