t/t5800: skip if python version is older than 2.5

This test script depends on the git-remote-testgit python script.  This
python script makes use of the hashlib module which was released in python
version 2.5.  So, add a new pre-requisite named PYTHON_2_5_OR_NEWER to
test-lib.sh and check for it in t5800.
