    gunixmounts: Do not leak libmount tables in _g_get_unix_mounts()
    
    Use mnt_context_get_mtab instead of using mnt_context_get_table(), since
    that's the recommended way of accessing mtab/mountinfo information, and
    also because that way the (struct libmnt_table *) will get automatically
    deallocated when calling mnt_free_context()
