    Update Meson requirement to 0.50.0
    
    Meson 0.50.0 was released on 10th March 2019. We should
    now be able to depend on it.
    
    In particular, Freedesktop SDK now contains 0.51.0[1] so
    this shouldn't break gnome-build-meta like last time (13948fda052e).
    
    Fixes the following warnings:
    
        WARNING: Project specifies a minimum meson_version '>=0.47' but uses features which were added in 
newer versions:
         * 0.49.0: {'/ with string arguments'}
         * 0.50.0: {'install arg in configure_file'}
