default-providers: Set the preferred provider for bluez based on version
bitbake will currently 'selecting bluez4 to satisfy runtime
libasound-module-bluez due to PREFERRED_PROVIDER_bluez4 = bluez4'
which in the case of bluez5 isn't correct.
This slightly unusual construct avoids this.
Ultimately this is a bitbake issue that needs fixing in
a better way but this means we can merge the bluez5 changes
until bitbake gets fixed.
