10 Hz seems excessive, so this patch adds a compile-time option

(This change could possibly be handled via a kernel boot option,
or even be made unconditional, but I opted for a compile-time
option for now.)

I don't think there is need to have an option for this. With HZ also
round_jiffies() could be used, it doesn't need to be exact.

(I also think the code should check that the button is held down for
a while before doing the shutdown, but that's a different issue.)
