Add test for CVE-2002-0059

CVE-2002-0059 was a double free in inflation. [0]

This makes sure we don't accidentally reintroduce it.

zlib-1.1.3 was download and fuzz tested using AFL[1].
This crashing case (test.gz) was discovered, and using gdb it was
confirmed to be a double free in the expected place.

The test script looks for a normal error exit (status code 1),
and fails if any other code is returned.
