podman version and --version: fix format, exit
Three unrelated fixes to version output:
* podman version --format json: was missing a newline
* podman version --format TEMPLATE: had too many newlines
* podman --version: would neither display version nor exit
if followed by a subcommand ('podman --version ps')
The first two were easy: I used my best tweezers to delicately
pluck and transfer the misplaced \n and place it where needed.
The third was a doozy of a rabbit hole. As best I can tell,
a workaround was added in root.go to override cobra's built-in
Version handling, apparently to avoid having cobra add "-v"
as an alias for "--version". As best I can tell, cobra only
does this if the "-v" shortcut is not already taken (at
least as of Nov 2019: https://github.com/spf13/cobra/pull/996 ).
Also as best I can tell that workaround is purely vestigial,
and removing it is safe. I've manually tested "-v" in podman run,
system df, and rm. I've run system tests.
