[OE-core] bluez-hcidump update

[Marko Lindqvist]

Before making bluez-hcidump automake-1.13 compatible, I'd like
it to update it to latest version. I made the trivial patch already.
It builds without problems, but someone able to do so should test
if it's fully functional. I'm worried about possible runtime
dependencies (latest version of main bluez package is documented
to be fully functional with kernel >= 3.5 only)
