Revert 42474 - Make repost form warning tabmodal on Gtk.

This is the Gtk version of http://codereview.chromium.org/969003.

BUG=26271
TEST=Go to http://www.cs.unc.edu/~jbs/resources/perl/perlcgi/programs/form1POST.html, hit Submit, then refresh. The warning sheet should be tabmodal, not windowmodal. Opening a login form (which is also tabmodal) while the warning is shown should not crash, neither should bringing up the warning while a login form is shown.
