git-gui: Make push remote combobox full width

When pushing changes, the Remote combobox for the Destination Repository does not take all available space in the layout. With long remote names, this causes the combobox to have truncated entries even though there is room to display them.

Anchor the remote_m combobox to both left and right edges of the grid cell and use the same padding as url_t for a consistent, dynamic layout.

Just wondering if I submitted this patch correctly and to the right place.
