Make liballoc_jemalloc work on CloudABI.

Browse Source 
The automated builds for CloudABI in dist-various-2 don't use
--disable-jemalloc, even though my original container image did. Instead
of setting that flag, let's go the extra mile of making jemalloc work.
CloudABI's C library already uses jemalloc and now exposes the API
extensions used by us.
