QEMU as recently switch its build system to use meson and the
./configure step with meson is more restrictive that the step used to
be, most installation path wants to be within prefix, otherwise we
have this error message:
ERROR: The value of the 'datadir' option is '/usr/share/qemu-xen' which
must be a subdir of the prefix '/usr/lib/xen'.
In order to workaround the limitation, we will set prefix to the same
one as for the rest of Xen installation, and set all the other paths.
For reference, a thread in qemu-devel:
"configure with datadir outside of --prefix fails with meson"
https://lore.kernel.org/qemu-devel/20200918133012.gh2...@perard.uk.xensource.com/t/
And an issue in meson:
"artificial limitation of directories (forced to be in prefix)"

I've tested the change with an oldish QEMU, qemu-xen-4.12, and the
layout of the tarball generated by osstest doesn't change.
