    init_main: Remove the placeholder SYSINIT
    
    This was initially introduced to ensure there is at least one entry so
    that the sysinit_set symbol is not undefined. Well now that the kernel
    has plenty of SYSINITs and it is unlikely we will have a kernel without
    any SYSINITs in future, then this placeholder is not relevant anymore.
