net-libs/webkit-gtk: security bump to 2.26.3, fix gtk-doc

Move gtk-doc building from USE=doc to USE=gtk-doc, as the latter is the
one to use now for when generating gtk-doc from scratch. Fix it with
perl-based gtk-doc by stripping out some tags in the docs completely;
this was already fixed upstream, but that fix seems dependent on newer
gtk-doc handling the markdown quoting that got added. So remove the
tags completely until we can depend on a newer gtk-doc that doesn't
have trouble with the upstream way.

Also a build fix for USE="wayland -opengl -gles2-only" (but remember:
you shouldn't disable both opengl and gles2-only on any real desktop
system).

+Upstream commit 41455af5d76a726f195838846b61e1693a2da99c is supposed to fix this,
+but it looks like it's not enough with older perl-based gtk-doc.
+Keep this extra patch only until we can't depend on a newer gtk-doc version, which
+should be retested whether this patch is unnecessary then.
