    Fix build with Meson 0.48.[0|1]
    
    https://github.com/mesonbuild/meson/commit/176af2c8c33e79732680ebb1e2a25b5cd7a51bb9,
    first included in Meson 0.48.0, breaks i18n.merge_file() when 'input' is
    a list. It's fixed by this commit
    https://github.com/mesonbuild/meson/commit/fe3efe0bc6f0bb0f282a2d1f7db4e72f16a3f51c
    which will eventually appear in 0.48.2/0.49 (whatever is the next
    release). In the meantime, we can work around this by specifying the
    input file as a scalar, not a list. (There are actually no translated
    strings in this .desktop file, anyway…)
    
    Fixes #64.
