Call __libc_init_malloc from scudo.

Currently, scudo doesn't call libc's malloc initialisers. This causes
problems with any functionality that relies on an initialised__libc_globals
inside of bionic malloc's stubs (e.g. malloc()).

This manifests in two ways (that I can think of):
 1. Dispatch tables don't work with scudo, so malloc_debug has never
 worked in an executable linked against scudo.
 2. Allocators that require initialisation and are called from bionic
 malloc's stubs (GWP-ASan) never get initialised.
