tests: Fix make check with GitHub action

The test scripts invoke anthytest.py whose unittest can skip tests
unless Display is available and the return value has been changed
since Python 3.12.1

No pycotap.__main__ and cannot be directly executed with `-m` option.

Fedora 39 Docker does not provide USER environment variable.

Fixes: ibus@b279e15
