local-build: Extract build_secure_image() as a separate library
Currently, all functions in `build_se_image.sh` are dedicated to publishing a payload image. However, `build_secure_image()` is now also used for repackaging a secure image when a kernel parameter is reconfigured. This reconfiguration is necessary because the KBS service address is determined after the initial secure image build. This commit extracts `build_secure_image()` from `build_se_image.sh` and creates a separate library, which can be loaded by bats-core. Signed-off-by: Hyounggyu Choi <Hyounggyu.Choi@ibm.com>
