Use appropriate styling for layouts
This change adjusts the theme of the layout to user's theme. It tries to use a dedicated one if available, otherwise it uses a generic fallback adapting to the current theme.
As a result of removing the workaround, it's now possible to run squeekboard directly from the build directory again.
