[PR] sys/shell: Fix uptime load for OS_TASK_RUN_TIME_CPUTIME [mynewt-core]

kasjer opened a new pull request, #3828:
URL: https://github.com/apache/mynewt-core/pull/3828

   When OS_TASK_RUN_TIME_CPUTIME is set, task run time is counted in cputime ticks (OS_CPUTIME_FREQ) while uptime load computation divided it by OS ticks, producing bogus load values.  Run time is also only 32 bits, so with 1 MHz cputime it wraps every ~71 minutes, and idle_ticks * 100 overflowed in 32-bit arithmetic.
   
   Use the unit that matches the run time configuration, accumulate idle task run time in 64 bits from the per-minute load monitor, and compute total load from os_get_uptime() in the same unit.
