Test launch script updated to run new tests as well.

I delete the LIBAVFORMAT_BUILD < 5231 branch, because I couldn't even find FFmpeg with
such a small build number, let alone test with it.

It has already been partially backported by #6199; this commit completes
the backport.

At the moment tests requre samples/data copied to source location from master branch.

This project is dead from the 1st September last year

The INSTALL_NAME_DIR property of a target specifies how a dynamic library should
be found on OS X.  If INSTALL_NAME_DIR is not specified the loader will search
relative to the standard search paths.  If specified it should either be
an absolute path or relative path prefixed with either @executable_path,
@load_path, or @rpath.  Specifying "lib" does not make sense here and
causes linking error as documented here:

This patch removes INSTALL_NAME_DIR everywhere it is set to "lib".
An alternate solution would be to set an absolute path like
"${CMAKE_INSTALL_PREFIX}/lib" or relative path like
"@executable_path/../lib".  However, if there is not specific need for
specifying a path, it is probably best left unset.

Fixed "Conditional jump or move depends on uninitialised value(s)" valgrind issue due to wrong pointer recalculation for zero level of pyramid.
