Kernel 4.4.6+ on RaspberryPi support .dtbo files for overlays, instead of .dtb.
Add support for both extensions for overlays (".dtb" and ".dtbo")
CAUTION: in IMAGE_CMD_rpi-sdimg, 'TMPDIR' is not set, causing
'STAGING_KERNEL_BUILDDIR' to not be expanded, causing get_dts() to not being
able to get the kernel version!
To avoid this problem, the kernel version is added in a new variable outside
the scope of IMAGE_CMD_rpi-sdimg, and its value passed to get_dts() and
split_overlays()!
