maint: adjust comments to avoid FP match on binary-operator-at-EOL

* src/ls.c (print_long_format): Reformat comment to avoid "=="
at end of line.
Also, "sortkey" is not a word: s/sortkey/sort key/.
* src/ioblksize.h: Likewise, for "|" from a shell snippet.
* src/runcon.c: Likewise, for "|" in grammar-like usage.
