python311Packages.mat2: disable test_all_parametred test

`test_all_parametred` test is too sensitive.
It frequently fails when exiftool is updated and adds support for new metadata.

Also migrated `unittestCheckHook` to `pytestCheckHook` to be able to disable
the test (not possible easily with unittest). We can do that safely
since pytest also supports unittest test suites.
