[oe] [meta-qt5][PATCH] qtmultimedia: Add support to enable/disable PulseAudio and ALSA

[Otavio Salvador]

The way QtMultimedia use to detect the PulseAudio and ALSA makes it
non obvious how to disable it. After researching how Gentoo does it
the 'done_config_<flag>' has been found. So now, we respect the distro
support for PulseAudio and ALSA.
