Yukihiro "Matz" Matsumoto 7dfd560df8 mruby-io: cap puts recursion depth to prevent C stack overflow ...

io_puts_ary recursed unconditionally on nested arrays. For cyclic
arrays (a = []; a << a; puts a) or pathologically deep arrays,
this caused a C stack overflow.

Add a depth cap (IO_PUTS_MAX_DEPTH = 16); on overflow, write
"[...]\n" and return, matching CRuby's behavior on cycles. The
pattern mirrors mruby-set's MAX_NESTED_DEPTH for the same problem
shape (pure C recursion not dispatched as a Ruby method).

Reported by OSS-Fuzz (clusterfuzz testcase 6233530857488384).
