Add an invalid file test case for oss-fuzz:9288.

The test case was constructed from the reproducer test case for
bug oss-fuzz:9288. I took the first two IVF frames in the reproducer
test case, fixed up the obu_size field (which was changed to 0 by the
fuzzer) of the third OBU in each IVF frame, and then repeated the two
IVF frames (so there are a total of four IVF frames in the test case).

Each IVF frame would cause libaom to leak 8 frame buffers if the bug
were present, so we would definitely run out of free frame buffers when
processing the third IVF frame.
