normalize tree entry modes to 0100644 or 0100755 when writing tree objects
semarie@ reported an error from go-git used by Cirrus CI: "57243613255d758e15b0f5ae1c960b970f0435f8: malformed mode (0100640)!" 'git fsck' has no problem with mode 0100640. But writing just the two most commonly used file modes should provide the best compatibility.
