lscpu: Add option --bytes

[sylvestre]

       -B, --bytes
           Print the sizes in bytes rather than in a human-readable format.

           By default, the unit, sizes are expressed in, is byte, and unit prefixes are in power
           of 2^10 (1024). Abbreviations of symbols are exhibited truncated in order to reach a
           better readability, by exhibiting alone the first letter of them; examples: "1 KiB"
           and "1 MiB" are respectively exhibited as "1 K" and "1 M", then omitting on purpose
           the mention "iB", which is part of these abbreviations.
