    build: bump glib 2.44 -> 2.58
    
    Bumping to make it easier in keeping compatibility with recent APIs
    without breaking stable distro releases.
    
    Fedora 31 (last stable): 2.62
    Debian 10 (last stable): 2.58
    
    Considering that we just released Grilo 0.3.12, next release can still
    be kept under current last stable distros releases.
