Sanitize tar file ownership, mode, and order

For reproducibility ensure all files in the dist tar file are owned by
root, and sorted by name.  Force the mode on all files to be writable
by the owner and not writable by group or user, by default.

Remove unnecessary execute permissions from build_w32.bat.
