coredump: format_corename: fix the "core_uses_pid" logic
I don't understand why the multi-thread coredump implies the core_uses_pid
behaviour, but we shouldn't use mm->mm_users for that. This counter can
be incremented by get_task_mm(). Use the valued returned by
coredump_wait() instead.
Also, remove the "const char *pattern" argument, format_corename() can use
core_pattern directly.
