support/testing: move the kernel config only used by test_edk2.py

The kernel config board/qemu/aarch64-sbsa/linux.config has never been in
use by qemu_aarch64_sbsa_defconfig, neither via
BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE, nor via
BR2_LINUX_KERNEL_CONFIG_FRAGMENT_FILES.

test_edk2.py is using the kernel config
board/qemu/aarch64-sbsa/linux.config. However, storing a kernel config
that is not used by qemu_aarch64_sbsa_defconfig, in a directory that is
"owned" by qemu_aarch64_sbsa_defconfig, is bound to cause confusion.

Therefore, move the config file to a new subdirectory:
support/testing/tests/boot/test_edk2/

This is similar to how e.g. test_grub.py has a subdirectory:
support/testing/tests/boot/test_grub/
where it keeps the kernel config that is only used by test_grub.py.
