patch 8.0.1326: largefile test fails on CI, glob test on MS-Windows

Problem:    Largefile test fails on CI, glob test on MS-Windows.
Solution:   Remove largefile test from list of all tests. Don't run
            Test_glob() on non-unix systems.  More cleanup. (Yegappan
            Lakshmanan, closes #2354)
