MSI: fix handling empty directories

Such empty directories are added e.g. by setup_native/Package_packinfo.mk
when using these configuration:

./autogen.sh --with-external-tar=/cygdrive/c/sources/lo-externalsrc --with-junit=/cygdrive/c/sources/junit-4.10.jar --with-ant-home=/cygdrive/c/sources/apache-ant-1.9.5 --enable-pch --disable-ccache --with-visual-studio=2019 --with-jdk-home="C:\Program Files\Microsoft\jdk-17.0.4.101-hotspot" --with-package-format=msi --with-ucrt-dir=/cygdrive/c/cygwin64/opt/ucrt/

Making after that produced this error:

: *****************************************************************
: ERROR: Reading from filehandle failed at C:/sources/core/solenv/bin/modules/installer/windows/file.pm line 967.
: *****************************************************************

because it tried to create MD5 hash of a directory.
