    fsverity: use register_sysctl_init() to avoid kmemleak warning

    Since the fsverity sysctl registration runs as a builtin initcall, there
    is no corresponding sysctl deregistration and the resulting struct
    ctl_table_header is not used.  This can cause a kmemleak warning just
    after the system boots up.  (A pointer to the ctl_table_header is stored
    in the fsverity_sysctl_header static variable, which kmemleak should
    detect; however, the compiler can optimize out that variable.)  Avoid
    the kmemleak warning by using register_sysctl_init() which is intended
    for use by builtin initcalls and uses kmemleak_not_leak().
