Fix goldfish manifest handling.

Copying in the manifest file breaks vintf_fragment based manifest
generation. This patch specifies the manifest.xml file using
the build system variable rather then copying it over the generated
file.

Shout out to mmaurer@google.com for finding this.

Test: Builds without conflict and produces the correct manifest.xml
