xen: Fix python libraries installation on multilib
xen: Fix python libraries installation on multilib

Fix install path for xen python libraries when multilib configuration is
activated (which is mandatory to compile xen for x86_64).
Depending on the version of Xen, the libraries are installed on lib or
on the nonarch lib directory so add both.
