Subject: [PATCH] Add support for making bundle items writable before fixing up.

This ensure that any bundle items are made user writable before
any attempt is made to alter them using install_name_tool. This is
because MacPorts/Fink/Homebrew don't install libraries as writable
so this fix is needed to allow fixup_bundle_item to work correctly
when using these package managers.
