Man pages: refactor common options: --shm-size

Mostly went with the podman-run version. For ease of review, I
kept the "you" word -- I will fix that in my in-progress
cleanup PR.

This affects lots of files, each of which had slightly different
wording, but this actually isn't as bad as it looks. The diffs
were minor, and I'm pretty sure the new refactored text applies
equally well to all the man pages.
