Subject: [PATCH] Open suse 3002.2 xen grub (#316)

* virt: convert xen pv XML generation test to pytest

* virt: better look for grub.xen when generating xen pv definition

openSUSE 15.3 and SLES 15 SP3 have removed the compatibility symlink for
/usr/share/grub2/x86_64-xen/grub.xen to
/usr/lib/grub2/x86_64-xen/grub.xen. virt._gen_xml() need to check which
is present and put in Xen PV VMs XML definition.
