RFR: JDK-8172577: Builds for OS X after build 149 does not include Java Mission Control.app

[Erik Joelsson]

Hello,

This patch fixes bug in the bundle logic, specifically the part that 
tries to work around files with spaces in them. In one of my recent 
changes in Bundles.gmk, I managed to break this completely.
