[PATCH] abilint: fix trivial typo when using abilint

[tangmeng]

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.

        * tools/abilint.cc (display_usage): End the usage message with a
        newline and remove invalid option description.
        (main): Add a newline after version string.
