postmarketos-mkinitfs: fix charging-sdl for kmsdrm devices (MR 2098)

This fix was pending since before charging-sdl was deprecated and still
provides value should anyone wish to pickup and improve charging-sdl
again.

charging-sdl currently does not check for devices using mesa, even
though it supports it in the same way as osk-sdl. Check for msa support
and set SDL_VIDEODRIVER in that case.

Also fix the font path, as it was reading both keyboard-font and
keyboard-font-size from osk.conf.
