[FFmpeg-devel] [PATCH v2 3/3] fate: Add .alt files so all tests pass on Ubuntu 20.04

[Alexander Strasser]

In commit bce5855afb25d318e090c2e6c16117f065458356 we avoided the
problem by using compression level 0. That fixed the problem, but
introduced a problem with older versioins of original zlib. This
caused differences 2 or more fate tests depending on the zlib version
used. See e.g. zlib commit 8ba393e70d984d902b15b9e6876f4d0d38ae4be8 .

After re-applying bce5855afb25d318e090c2e6c16117f065458356 this
patch fixes the 2 mentioned cases for older zlib versions by
allowing an alternative reference file. The files accommodate
for the bug in the older version.
