lib/dim: add KUnit test for dim_calc_stats()

Browse source

Add a KUnit suite for the DIM library that checks the packet, byte,
event and completion rates computed by dim_calc_stats(), including
counter wraparound and windows whose byte or packet count times
USEC_PER_MSEC does not fit in 32 bits. The latter cases fail on 32-bit
architectures without the previous commit.
