overlay: fix mouse cursor getting stuck in wrong shape when leaving and coming back to window (#283)

Browse Source 
## Link to GitHub Issue, if one exists
Fixes #27 

## Description of change
In standalone configurator mode, when a mouse cursor moves outside the
window and comes back, it may get stuck in the wrong cursor type (e.g.,
get stuck in horizontal resize mode). This is a side effect of software
rendering we do that doesn't deal nicely with mouse events (i.e., not at
all).

## Compiling
Should be fine.

## Testing
Testing spicecfg, spice -cfg, spice64 -cfg, and in-game overlay.
