    kernel: include CONFIG_KEXEC_SIG in configs
    
    Seeing failure to build because of missing symbols related to provisioning
    CONFIG_KEXEC and signed images.  Without this, if you set
    CONFIG_KERNEL_KEXEC=y and try to build, target/linux will hang at:
    
    scripts/kconfig/conf  --syncconfig Kconfig
    ...
    kexec system call (KEXEC) [Y/n/?] y
    kexec file based system call (KEXEC_FILE) [Y/n/?] y
    Verify kernel signature during kexec_file_load() syscall (KEXEC_SIG) [N/y/?] (NEW)
