Keep the same area file (areas.bbs) mode flags (permissions)

When executing area manager requests that alter the area file, the temp area
file created (with mkstemp) had mode 0600 (owner read/write only). The sysop
very possibly had different permission flags they want to keep for their area
file, so copy the mode flags from the original area file to the temp/new area
file.
