[docs] Reformat -help output for help2man

Browse Source 
This commit slightly changes the format of the "Usage" strings in CLI
`-help` messages to meet the expection of the help2man tool, which we
use to generate man pages. On the way, we remove a few calls to
`strprintf()`, which became superficial after commit 32fbfda.
