[OE-core] [PATCH 2/2] libsdl2: disable sndio explicitly to avoid inconsistent result

[Chen Qi]

Explicitly disable sndio to avoid inconsistent result on different
hosts having or not having libsndio.

This must be done if we take into consideration of eSDK.

I built eSDK on Ubuntu 14.04 which has libsndio installed, and then
installed the eSDK on Fedora 27, which does not have libsndio. In
fact, on Fedora 27, I even cannot find libsndio in its repo.

The problem happens when trying to use `devtool runqemu'. The qemu
binary built on Ubuntu 14.04 needs to link to libsndio, and thus
the following error.

  runqemu - ERROR - Failed to run qemu: /path/to/qemu-system-x86_64:
            error while loading shared libraries: libsndio.so.6.1:
            cannot open shared object file: No such file or directory

So explicitly disable sndio for libsdl2 to avoid the above problem.
