[virt-tools-list] [PATCH virt-viewer] Load ui files first from installed location

[Jonathon Jongsma]

virt_viewer_util_load_ui() looks first in the current directory, and then looks
in the system data dirs for a ui file to load, but if you install virt-viewer in
a different prefix, it will load the system UI file rather than the one from the
install prefix. Try to load the ui file from pkgdatadir first.
