sort: remove procfs dependency and fix percent parsing bugs in parse_size

[ChrisDryden]

There were quite a few bugs in the implementation of the memory sorting option and it was not working as expected outlined in: #10803 I started investigating it to see if it was possible to remove this dependency because it brings in a bunch of other dependencies like chronos and we only use the procfs dependency just for this one function.

When I investigated how this function was implemented, it was simply reading the file iterating through all of the lines and splitting. Whats great is that since it wasn't working in the first place it means that theres no way this PR could introduce a regression.

These are all of the dependencies that would be removed from all of the parse_size users:

procfs, procfs-core, chrono, iana-time-zone, flate2, miniz_oxide, adler2, crc32fast, simd-adler32.

Fixes: #10803
