[virt-tools-list] [virt-viewer v2] win32: Look up translations relative to installation directory

[Christophe Fergeau]

On Windows, we can't use bindtextdomain(GETTEXT_PACKAGE, LOCALE_DIR); as
LOCALE_DIR is a compile-time constant, while the location of the
translations will be dependant on where the user installs virt-viewer.
This results in an untranslated virt-viewer UI on Windows. This commit
calls bindtextdomain() with a directory which is relative to the
installation path so that translation are properly found.
This is similar to what spice-gtk is doing:
