    glocalfile: Fix leak of FS type on some platforms
    
    fstype is a const char*, and is passed to
    g_file_info_set_attribute_string(), which takes a copy of it. There’s no
    need to g_strdup() the FS type from various statfs/statvfs buffers
    beforehand, given that the buffers are valid for the duration of this
    function.
