scripts/link-vmlinux.sh: source variables from KCONFIG_CONFIG

Its possible to superseed the config file with KCONFIG_CONFIG and have completely no .config in the tree. The current script is sourcing .config in every case, so the kernel will never build succesfully. This patch fixes that issue by sourcing KCONFIG_CONFIG instead.
