contrib: Unify quoting in error messages

This fixes error messages to display the contents of variables rather
than the variable name by replacing backticks with single quotes (m4
eats backticks). It also removes $"" localization from error messages to
eliminate security holes.

For instance, `rankmirrors nonexistent_file' will now display:
	'nonexistent_file' does not exist.
rather than:
	$1 does not exist.
