abilint: fix trivial typo when using abilint

When using the abilint command, several problems were found:
1.When abilint prints its version information, it does not terminate
it with a newline.
2.There is a spelling error, the path is mistakenly written as patch.
3.There are extra fields in the help option.
4.Inappropriate and confusing option description.

	* tools/abilint.cc (display_usage): Correct the errors and
	redundant content in the help information.
	(main): Add a newline after version string.
