[OE-core] QEMU recipe cleanup

[Paul Eggleton]

Hi all,

I was looking into Yocto bug #2020 today and I noticed we have some "old" QEMU 
recipes kicking around. 0.15.1 is the latest version which AFAIK I've been 
using since it was merged mid-October last year, and it seems to be working 
fine. We also have 0.14.0 and a _git recipe which claims (via manually set PV) 
to be 0.14.0 as well.

Do we need to keep all of these?

Cheers,
Paul
