[CMake] Problem with removing directories containing soft links on MSYS

[Volo Zyko]

Additionally investigated that the following also fails:

$> test_dir=$PWD/cmake

$> mkdir -p $test_dir/z
$> ln -s $test_dir/z/ $test_dir/a

$> cmake -E remove_directory $test_dir

In this case $test_dir/z is not removed at all.

Also, I checked cmake 3.5.1 and 3.9.2.
