7099119: Remove unused dlinfo local variable in launcher code

[Shi Jun]

Hi all,

Previously 7099119 is fixed in the following changeset: 
http://hg.openjdk.java.net/jdk8/tl/jdk/rev/dd55467dd1f2, but this change 
is lost during the Mac port merging changes 7113349 and 7146424.

Hereby I raise this thread again.
