Title: Make cpuload correct and more efficient for all configurations of NuttX

Currently cpuload assumes there are only 2 static threads - idle and init, this
is true only for "basic" config of NuttX, as there can be 3 more static threads:
paging, work0 and work1 - depending on config. In such cases cpuload
would mistake one of them for init (which in fact is always last), giving
incorrect results to "top"
