[lacros] Fix blurry Lacros window when display scale is fractional

This CL makes sure that LaCros windows receive big enough
wl_output.scale from exo when display scale is fractional by rounding it
up to the closest integer.

This is similar to how other compositors (Mutter, Sway) deal with
fractional scaling: clients are only aware of integer scaling and the
actual contents of windows are scaled down on the compositor side
(it's already done in Aura in our case).
