bluetooth.bbclass: simplify recipe inference of bluetooth provider

Defines ${BLUEZ} to be the provider of bluez services as specified by
DISTRO_FEATURES.

Example recipe fragment:
  inherit bluetooth
  PACKAGECONFIG ??= "${@bb.utils.contains('DISTRO_FEATURES', 'bluetooth', '${BLUEZ}', '', d)}
  PACKAGECONFIG[bluez4] = "--enable-bluetooth,--disable-bluetooth,bluez4"
  PACKAGECONFIG[bluez5] = "--enable-bluez5,--disable-bluez5,bluez5"

+# Avoid code duplication in bluetooth-dependent recipes.

+# Define a variable that expands to the recipe (package) providing core
+# bluetooth support on the platform:
+# "" if bluetooth is not in DISTRO_FEATURES
+# else "bluez5" if bluez5 is in DISTRO_FEATURES
+# else "bluez4"
+
+# Use this with:
+#  inherit bluetooth
