bump crengine: HTML and rendering fixes (#3992)

- Fix getting xpointer to current page
- epub.css cleanup
- fb2def.h update
- Fix a few edge-case rendering issues
- Fix border being drawn in spite of 'border-width: 0'

Also update Wikipedia epub.css stylesheets regarding
recent HTML fixes and enhancements.
Remove "Remove all borders" workaround tweaks, as it's
now fixed.
(Unit tests failure to be fixed in upcoming commit)
