Takuro Ashie beff0bd0f9 desktop-shell: Fix wrong initial position of input panel
When the surface type of input panel is set as an overlay panel, it's
expected to be shown at near the input cursor. But the current
implementation shows it at center-bottom on the desktop at first then
move it to the correct position while typing.
