Yukihiro "Matz" Matsumoto 66f438d8fe mruby-bin-debugger: return on OOM in mrb_debug_set_break_method

mrb_debug_set_break_method() freed set_class after mrdb_strdup() of
method_name failed but did not return. Execution continued into
alloc_breakpoint(), which on failure double-freed set_class, or on
success stored the dangling pointer in the breakpoint table for later
use-after-free. Return MRB_DEBUG_NOBUF immediately after the free.

mrdb_strdup uses mrb_malloc_simple which returns NULL on OOM (it does
not raise), so the NULL check is reachable in practice.

close #6851
