lvgl: Support both fbdev and wayland backends

Browse Source 
The LVGL can be operated on top of fbdev as well as on WL compositor.
Support both, which is a matter of configuring lv-drivers package per
required backend. Determine the backend from DISTRO_FEATURES, since
both 'wayland' and 'fbdev' are valid DISTRO_FEATURES. Add a bit more
sed hacking of the configuration, which enables either FBDEV or WL
backend. One notable item here is the enablement of EVDEV support,
which is required for FBDEV backend, so in case FBDEV is enabled, so
is EVDEV.
