xen/Makefile: remove all temporary files for every architecture

Execute the clean target for both arm and x86 architecture.

When trying to build Xen for a different architecture in the same
tree, the command make clean will only remove temporary files for
the host architecture.
This will lead a compilation error when trying to build ARM64 and
ARM32 Xen in the same tree.
