Take cluster size into account when calculating zip extracted size.

Browse source 
Allow passing an (optional) cluster size to round up all file sizes when
calculating the total size of an extracted zip archive. This allows to check if
the space on disk is actually sufficient without relying on an arbitrary
headroom value which might be wrong. Addresses FS#12195.
