elf: Move __rtld_malloc_init_stubs call into _dl_start_final

Calling an extern function in a different translation unit before
self-relocation is brittle.  The compiler may load the address
at an earlier point in _dl_start, before self-relocation.  In
_dl_start_final, the call is behind a compiler barrier, so this
cannot happen.
