[meta-freescale] [meta-fsl-arm][PATCH] fsl-vivante-kernel-driver-handler.bbclass: Fix kernel config when graphics kernel module config is changed

[Tom Hochstein]

Changes to the kernel config can only be applied to the defconfig since
the do_configure_prepend in fsl-kernel-localversion.bbclass throws away
the build/.config file.
