ps: Add PSS and USS fields

The library added smaps_rollup fields in the referenced commit. This commit exploits the new fields to give pss and uss options. These options were first proposed back in 2015 by Petr Malat and, with the library update, they are finally made it into ps. Why use proportional or unique segment size? It is argued that these give a better idea of the "real" memory usage of a process.
