    fileutils: Override umask for gs_file_create()
    
    The entire point of this API is to atomically create a file
    with the given mode; we need to fchmod() in order to get
    exactly what is specified.
    
    This fixes gnome-ostree which uses ostree to check out trees; we were
    losing the g-w bit on checked out files.
