fuchsia: Create package with stripped binaries.

Per "Prebuilt CIPD packages in Fuchsia" [1], the prebuilt
package containing ELF binaries need to be stripped.
The unstripped binary can be provided in a separated symbol
package.

This change modifies the releasepackage.py script to make
it produce two separated CIPD package: libvulkan_goldfish/x64
and libvulkan_goldfish/debug-symbols-x64.
