It's not about just disabling the vout at runtime - libvlcjni.so requires
libEGL.so in order to be loaded at all, so even if we don't use the vouts
that use EGL, we won't be able to load the JNI lib at all on pre-2.3
devices. We would have to do a separate APK build for pre-2.3 devices with
these modules disabled.
Then again, since the APK only supports armv7, and there IMO are not very
many armv7 devices that haven't gotten updated to 2.3, so there might not
be much use for it. Separate builds for armv6 might be built with these
