[oe] minimal distro, console image and bluez

[Frans Meulenbroeks]

When building console image for minimal I get:

ERROR: Multiple .bb files are due to be built which each provide
bluez-libs (/home/hudson/jobs/OE_test/workspace/openembedded/recipes/bluez/bluez4_4.42.bb
/home/hudson/jobs/OE_test/workspace/openembedded/recipes/bluez/bluez-libs_3.36.bb).
 This usually means one provides something the other doesn't and should.

Guess minimal needs to set a preference...
