[PATCH 1/2] yama: Make sysctl table const

Since commit 7abc9b53bd51 ("sysctl: allow registration of const struct
ctl_table"), the sysctl registration API allows for struct ctl_table to be
in read-only memory. Move yama_sysctl_table to be declared at build time,
instead of having to be dynamically allocated at boot time.
