tty: Make sysctl table const 



Since commit 7abc9b53 ("sysctl: allow registration of const struct
ctl_table"), the sysctl registration API allows for struct ctl_table to be
in read-only memory. Move tty_table to be declared at build time, instead
of having to be dynamically allocated at boot time.
