[yocto] Use of BBPATH in a layer.conf file.

[Scott Garman]

Hey folks,

Robert Day has brought up an inconsistency in the way we append to 
BBPATH within a couple of our layer.conf files.

In meta-hob, meta-yocto-bsp, and meta-intel, we do:

BBPATH := "${BBPATH}:${LAYERDIR}"

but in meta-yocto, we do:

BBPATH := "${LAYERDIR}:${BBPATH}"

Unless someone explains to me that it's necessary to use this different 
ordering in meta-yocto's layer.conf, I will submit a patch to make this 
more consistent.

Scott
