[htop-general] Patch - fix keys used to change nice value

[Gadiyar, A. <ga...@ti...>]

The help text says F8, -, and ] are used to raise priority, while F7, +,
and [ are used to lower priority. However, the code reverses F7 and F8.

Either fix the help text or fix the code to do what the help text says
