    Revert "gstdio: #include fcntl.h on UNIX in gstdio.h"
    
    This reverts commit 6f8073d44ab02e9d641ccbe8c2640796ca1456ca.
    
    As per further discussion on bug #781598, we can’t do this in GLib,
    since fcntl.h is not guaranteed to be present on all Unix systems. Users
    of GLib *must* do a header check (for example, using AC_CHECK_HEADERS)
    and #include fcntl.h themselves.
