From: "Yann E. MORIN" <yann.morin.1998 at free.fr>
If $(KERNEL_SOURCE_CONFIG) is read-only (eg. because Buildroot's source
dir is), the rm of $(KERNEL_ARCH_PATH)/configs/buildroot_defconfig will
either fail, or prompt the user, both of which we want to avoid.
Make it writable by using $(INSTALL).
Fixes: #4363
