fix(cli): inconsistent system hash between sessions

Browse source 
sxhash doesn't guarantee hashes are consistent across Emacs sessions, so
use md5 instead. Also simplifies what's getting hashed;
`system-configuration` is a sufficient substitute for both `system-type`
and what I wanted to glean from changes in
`system-configuration-features`.
