Subject: [PATCH] graphics: add check for qemu modules in spice graphics
 detection

For SLE and openSUSE qemu, starting with v5.1, spice and spice related
qemu modules have been split away from the main system emulator and
are packaged as Recommends, meaning that they may not be present.
Up to now virt-manager has assumed spice is available for x86 qemu, but
that is no longer the case. Unfortunately the standard libvirt feature
detection can't yet help us out here, so we leapfrog libvirt by doing
our own detection of whether the qemu modules needed to support the
default guest install using spice, usb redirection, and qxl video are
present.
With v5.2, some additional qemu modules are also required, so we add
a separate detection for that version, and add corresponding additional
module checks.
