[PATCH 2/2] configure: passthrough for audio-{drv,card} and logic cleanup

[Carlo Marcelo Arenas Belon <carenas@sajinet.com.pe>]

Avoids reformatting for the options that are send verbatim to qemu's
configure and add a passthrough for qemu options that use a space
separated list of options like the list for audio drivers enabled
or the list for audio devices emulated.
