CMake: Add support for building and installing xz with translations.
If gettext tools are available, the .po files listed in po/LINGUAS are converted using msgfmt. This allows building with translations directly from xz.git without Autotools. If gettext tools aren't available, the Autotools-created .gmo files in the "po" directory will be used. This allows CMake-based build to use translations from Autotools-generated tarball. If translation support is found (Intl_FOUND) but both the gettext tools and the pre-generated .gmo files are missing, then "make" will fail.
