[LTP] [PATCH 1/1] Docparse: Escape | in table content

[Petr Vorel <pvorel@suse.cz>]

31708e815 added | in values displayed in table, which unescaped breaks
table formatting.

NOTE: Due asciidoc{,tor} markup design it's difficult to easily escape markup
handling only this particular case.

Fixes: #754
