Kyle Evans 1426fd6cff rtld: implement _dl_iterate_phdr_locked
Some sanitizers need to be able to use dl_iterate_phdr() after stopping
the rest of the process, but it's very hard to do so reliably as a
non-participant in the main logic of the program.

Introduce _dl_iterate_phdr_locked to bypass the locking that's normally
required for dl_iterate_phdr() and slap some scary warning on it.  It
will remain undocumented and probably shouldn't be used for anything
else.
