fsl-kernel-localversion: Add preconfigure dependency on do_unpack
Even if 'externalsrc' is used, SRC_URI may specify a 'defconfig'.
However as the use of 'externalsrc' will do away with the do_patch
task, do_preconfigure is in risk of being run before the defconfig
is copied to the build directory. This patch adds a second dependency
on 'do_unpack' that makes sure this does not happen.
