RFR JDK-8167328: jar -d m.jar hangs

[Xueming Shen]

Hi,

Please help review the change for #8167328

issue: https://bugs.openjdk.java.net/browse/JDK-8167328
webrev: http://cr.openjdk.java.net/~sherman/8167328

It appears the desired behavior is to throw the error + help msg if the
option "--print-module-descriptor"/ "-d" is specified with some extra
file names.

Thanks,
Sherman
