setup-defconfig.inc: implement config fragments by using in-kernel script

* Use in-kernel merge_config.sh script and KERNEL_CONFIG_FRAGMENTS list
* Move copying provided defconfig from own task to do_configure() for atomicity
* Don't use curly brackets for shell variables to avoid conflict with Bitbake
