Subject: [PATCH] update dump978.sh to fix dump978-maint.sh and feed
 dump1090-mutability

dump978-maint.sh starts up dump978 and pipes output to uat2json (that updates dump978.php) and is then piped to uat2esnt and netcat (to dump1090-mutability).

However uat2json does not echo stdin to stdout output, meaning uat2esnt gets no input, and nothing makes it to dump1090-mutability.

This changes dump978-maint.sh to bash and uses tee to fork dump978's output to both uat2json and uat2esnt so messages make it to dump1090-mutability.
