Fix "resize to fit" when all clicks are forwarded

To resize the window to fit the device screen, it is possible to
double-click in the "black bars".

This feature was mistakenly disabled when --forward-all-clicks was set.

Instead, disable it only if mouse relative mode is enabled (AOA or
UHID), because in that case the mouse cursor is on the device.
