patch 9.1.1693: tests: test_filetype fails in shadow dir

Commit: https://github.com/vim/vim/commit/de6e5601507a69067a429e79d0476badb664bb83

patch 9.1.1693: tests: test_filetype fails in shadow dir

Problem: tests: test_filetype fails in shadow dir
(after v9.1.9.1.1687)
Solution: Use a custom test that does not rely on configure.ac
being existing in the upper directory tree.
