Update to remove direct include of jemalloc_new.

In order to support scudo for non-svelte malloc and jemalloc5 for
svelte malloc, do not include jemalloc_new directly. Move that to
the export_include_dirs for libjemalloc5.

Also, change the way to enable scudo so that it only enables it
for the non-svelte config for now.
