qt5virtualkeyboard: add hashes of 3rd-party licenses

Add missing license hashes for those three third-parties:

	- src/virtualkeyboard/3rdparty/openwnn/NOTICE
	- src/virtualkeyboard/3rdparty/pinyin/NOTICE
	- src/virtualkeyboard/3rdparty/tcime/COPYING

Fixes:

	>>> qt5virtualkeyboard 5.11.1 Collecting legal info
	LICENSE.GPL3: OK (sha256: 8ceb4b9ee5adedde47b31e975c1d90c73ad27b6b165a1dcd80c7c545eb65b903)
	ERROR: No hash found for src/virtualkeyboard/3rdparty/openwnn/NOTICE
	ERROR: No hash found for src/virtualkeyboard/3rdparty/pinyin/NOTICE

In order to make this possible, we use a different hash file for the
old version (2.0, used with Qt 5.6) and new (5.11, used with Qt 5.11)
versions of qt5virtualkeyboard.
