System tests: help messages: check required-arg

If a usage message is of the form '... [flags] ARGNAME',
where ARGNAME is all-caps and not in brackets, it must
be a required argument. Try running podman subcommand
without ARGNAME, and make sure that podman bails out
with an informative message. (Since this message is
freeform in each subcommand, not Cobra-generated,
we have a lot of possible variations to check for).

Fix podman login/logout Use messages to indicate that
REGISTRY is now optional (as of #5233).

This test has actually been in place for over a year but
due to a typo on my part -- a missing space -- it was
not being run. "For want of a space, much testing was lost".
