upgpkg: minecraft-server 1.11.2-3
Harden management script against code errors and faulty user input by
disallowing the use of undeclared variables ('set -u') and returning on
unhandled errors of invoked programs ('set -e') plus:
* Circumvent '$?' everywhere by using 'if $()' instead.
* Deprecate 'expr' in favor of shell built-ins and '`' for '$()'.
* Use more quotes around variables.
