docs: Fix argument formatting in ovs-appctl(8) man page.

The synopsis is not printed out correctly, because "``" is not spaced out from the text correctly. Use the "\ " to separate. This symbol will not be rendered, but allows to separate the formatting inside rST. Also, arguments in man pages are typically underlined instead of being normal text in triangular brackets. Fixing a couple other minor issues along the way. Acked-by: Simon Horman <[email protected]> Signed-off-by: Ilya Maximets <[email protected]>
