Fix trivial typo when printing message

When abilint prints its tips information and abisym prints its
version string, it does not terminate it with a newline the way
that other commands do.

	* tools/abilint.cc (main): End the 'FILE_TYPE_UNKNOWN' tips with a
	newline.
	* tools/abisym.cc (main): Add a newline after version string.
