patch 9.0.1947: Bash Expansion test fails on Windows/MacOS

Problem:  Bash Expansion test fails on Windows/MacOS
Solution: Disable Test_glob_extended_bash for now

This test doesn't work on Windows even if bash can be executed, since
the globstar functionality has only been enabled in Unix builds of Vim
(Commit 9eb1ce5315, patch 9.0.1946).
