Fix: Memory usage using raw numbers

Use free without -h to get raw numbers to report correct memory usage,
otherwise when the free memory is a lower order of magnitude than the
total memory, e.g., the free memory is in MiB and the total memory
is in GiB, then the human-readable free memory number will be too
large compared to the total memory number.
