[PATCH] meson.build: fix building of Xen support for aarch64

[Alex Bennée <alex.bennee@xxxxxxxxxx>]

Xen is supported on aarch64 although weirdly using the i386-softmmu
model. Checking based on the host CPU meant we never enabled Xen
support. It would be nice to enable CONFIG_XEN for aarch64-softmmu to
make it not seem weird but that will require further build surgery.
