Change magnifying glass cursor from pointer to default (arrow)

Before WVUI loads, we show a magnifying glass at the start of the input
that visually mimics the magnifying glass start icon in WVUI's typeahead
search component. Unfortunately, this element is a submit button in
Vector instead of the inert span element used in WVUI.

Although the submit button is useful for no-js users, it might be
confusing for js users. Ideally, an inert element like a span would be
used instead, but that deserves its own ticket. As a temporary easy
stopgap, changing the cursor to be an arrow instead of the pointer might
make this less confusing and discourage clicks to it.
