[PATCH 2/3] cputime: Allow dynamic switch between tick/virtual based cputime accounting

Allow to dynamically switch between tick and virtual based cputime accounting. This way we can provide a kind of "on-demand" virtual based cputime accounting. In this mode, the kernel will rely on the user hooks subsystem to dynamically hook on kernel boundaries. This is in preparation for beeing
