[Buildroot] [PATCH] gst-plugins-base: make alsa plug-in configurable

[Sven Neumann]

It may be desirable not to use the alsa sink for playback
even though alsa-lib is installed. So make this a configuration
option. This also takes care of selecting the proper options
for alsa-lib
(BR2_PACKAGE_ALSA_LIB_MIXER and BR2_PACKAGE_ALSA_LIB_PCM).
