package/mpd: ensure expat is enabled when BR2_PACKAGE_MPD_UPNP_NPUPNP=y
Just like BR2_PACKAGE_MPD_UPNP_PUPNP needs expat and curl support,
BR2_PACKAGE_MPD_UPNP_NPUPNP also needs expat and curl. curl was
already selected, but not expat. It didn't cause any visible issue, as
BR2_PACKAGE_MPD_UPNP_NPUPNP selects BR2_PACKAGE_LIBNPUPNP, which
itself select BR2_PACKAGE_EXPAT. But as mpd directly checks for the
availability of expat, it makes sense to also select it directly.
