GTK: Elide the EV bubble to approximately half of the location bar when really long.

This only counts the non-icon area of the location bar. Unlike the windows
implementation, the minimum size of the EV bubble is 10 characters instead of
150px.

BUG=42856
TEST=Visit https://www.barbican.org.uk/eticketing/index.asp and make the window smaller.
