Nightly build's jsc doesn't work without DYLD_FRAMEWORK...
https://bugs.webkit.org/show_bug.cgi?id=79065

Reviewed by Darin Adler.

Fixes the build process so the depencencies of the jsc binary are
modified before its copied to its target directory. In this way
jsc should always use relative reference to the JavaScriptCore
libraries.

* JavaScriptCore.xcodeproj/project.pbxproj: Fixes the commands in
the "Copy Into Framework" target.
