[glib: 4/5] gio: Remove fam file monitor support

[Sebastian Dröge <sdroege src gnome org>]

commit 6aa210e6af965a972a1c3a03e9abd556c45872ac

    gio: Remove fam file monitor support
    
    libgamin was last released in 2007 and is dead
    [upstream](https://gitlab.gnome.org/Archive/gamin). Distributions may
    still ship it (although Fedora no longer does), but we want people to
    use inotify on Linux since it’s actively supported.
    
    BSDs use kqueue. Windows uses win32filemonitor.
    
    FAM might still be used on some commercial Unix distributions, but there
    are no contributors from those distributions, and certainly no CI for
    them to prevent regressions.

    Fixes: #2614
