Make Rockbox Utility error out if the zip file its going to install requires more space than left on the device. Calculation adds a safety space of 1MB so you need at least 1MB more free space than the extracted archive. This also catches differences due to the size calculation not taking cluster losses into account. Free disk space is also displayed in the sysinfo dialog. Fixes FS#9417.
