Fix: Make test_dwarf and test_bin_info tests work out-of-tree

When building out of tree, these tests fail to find the test data.
This patch makes them (their _complete wrappers, actually) generated
by Autoconf, so the proper path to the test data (which is in the
source directory) can be written.

We can also get rid of SCRIPT_LIST and it's custom rules.
