In preparation of removing the legacy Xen driver, move the xmconfig tests from WITH_XEN to WITH_LIBXL. Even though the legacy driver will be removed, we'll want to maintain the ability to convert xm config to XML. Requires fixing up the tests to account for different behavior of Xen vs libxl post parse functions. For consistency with other Xen config tests, change the <os> arch to x86_64. There is some test file fallout due to differences in handling of default values between xend and libxl.

xend was deprecated in Xen 4.2 and removed from the Xen sources before the Xen 4.5 release. The last Xen release to contain xend was Xen 4.4, which was retired upstream in March 2017. Remove xend support from libvirt since it is unrealistic to use modern libvirt with ancient Xen.
