[Buildroot] [PATCH 12/14] package/pulseaudio: add optional support for udev

[Bernd Kuhls]

When udev was compiled before, pulseaudio will use it as optional
dependency:

$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/lib/pulse-8.0/modules/module-alsa-sink.so | grep NEEDED
[...]
 0x0000000000000001 (NEEDED)             Shared library: [libudev.so.1]
[...]
