sysupdate: use the rc -b flag to keep sysupdate in memory when /rc/bin/sysupdate gets updated itself during a sysupdate, rc gets confused when continuing reading the original file, but it gets data from the updated file causing confusion. the -b flag forces rc to read the original file as a whole before starting execution preventing this issue. updating this should be fine as the file has been shrunk from 230 bytes to 224 bytes.
