[PATCH] qemu: Add alsa PACKAGECONFIG and cleanup native/nativesdk DEPENDS

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Converting this dependency to become a PACKAGECONFIG makes sense. Since
there is a "," in the configuration option, its not quite as straightforward
as normal.

Also clean up the native and nativesdk DEPENDS and set the PACKAGECONFIG
entries to match the old behaviour by default.
