set package name/version to enigma2/2.4,

prefer pkg-config files over <package>-config when looking for freetype and sdl libraries (fallback to old behaviour if required),
use freetype pkg-config file as an indication for a library newer than 2.0.x (also set -DFREETYPE2 in this case),
create an AM_CONDITIONAL 'WITH_SDL' to be used by Makefiles
