[yocto] kernel dev manual: KBRANCH_DEFAULT is dead, jim.

[Robert P. J. Day]

  ch 3 still refers to the variable KBRANCH_DEFAULT even though that
variable was tossed back in march of 2014:

commit e631fc989b08873f559c5927117301294f04298c

    kernel-yocto: remove KBRANCH_DEFAULT

    KBRANCH_DEFAULT is no longer used, so we can remove it from all
    recipes (and it won't be missed).
