libtimeinstate: support cpufreq fast switching

In order to support kernels that use fast frequency switching, the
time_in_state BPF program needs to know which CPUs are members of
which cpufreq policies. Add logic to startTrackingUidCpuFreqTimes() to
write this information into a BPF map in order to make it available to
the BPF program.

Test: libtimeinstate_test passes
