mingw: handle the missing POSIXPERM prereq in t9124

On Windows, the permission system works completely differently than
expected by some of the tests. So let's make sure that we do not test
POSIX functionality on Windows.

This lets t9124-git-svn-dcommit-auto-props.sh pass in Git for Windows'
SDK.
