Fix failure of fns-tests-collate-strings on Cygwin

* test/src/fns-tests.el (fns-tests-collate-strings): Use
en_XY.UTF-8 instead of en_DE.UTF-8 as an example of an invalid
locale; en_DE.UTF-8 is actually a valid locale on Cygwin.
Note: The test will still fail on Cygwin releases < 3.5
because of a Cygwin bug.  (Bug#62420)
