Bug 546870 - [GTK3] Scrollbar broken after resizing JavaDoc hover

When resizing a JavaDoc hover, the horizontal scrollbar painting is
broken if GTK overlay scrollbars are disabled.

This change specifies word-wrap instead of scrolling upon text overflow,
for the .html of the JavaDoc hover. This change is applied only if the
OS is Linux.
