Luks password not handled correctly

Hi,

The architect installer will not handle luks password correctly, for example if the password contains "*" character it will be interpreted by shell to files names in working directory.

I've spent 24hr installing and reinstalling before I identified the problem.

For some reason I cannot make a pull request here, fix is easy:

sed -i 's/echo $PASSWD/echo "$PASSWD"/' /usr/lib/manjaro-architect/util-disk.sh

Thanks.
