Renamed the recipe to 0.12.4.
Moved the patches directory to qemu-0.12.4 - when it was named
qemu-0.12, bitbake silently ignored the patches, and only failed when
it came time to apply them.
Added a FILESDIR to the git recipe and changed its PV to 0.12.4 so it
can use the same patches as the normal recipe for now.
Removed the series file - it wasn't needed.
