check for available space, excluding root reserved blocks
We are checking the space requirements for ages, but the check uses the
free blocks count, which includes the blocks reserved for usage by root.
Now that we use an unprivileged user it has no access to these blocks
anymore – and more importantly these blocks are a reserve, they
shouldn't be used by apt without special encouragement by the user as it
would be bad to have dpkg run out of diskspace and maintainerscripts
like man-db skip certain actions if not enough space is available
freely.
