Find a library with a good .preinit_array

[mjhouse]

We need to find a shared library for testing that has a good preinit array.

1. Find a shared lib with a .preinit_array section that has at least a few items in it (use readelf -S lib.so to check- look at the size and entsize fields)
2. Use the dump.sh script to add it to the repo.
3. Add it to the dump_all.sh script (just in case we need to rebuild test files while tweaking the dump.sh script)
