[PATCH/RFR&A] Do not rename read-only files during a push

This is on the "merged to 'master' soon" list, but has a small amend by me (namely, chmod of final pack is done only when we are writing the final pack, i.e. reading from stdin) to fix breakages observed in tests. It would be nice to get a final Ack before moving it to 'master'.

From: Petr Baudis <pasky@suse.cz>

Win32 does not allow renaming read-only files (at least on a Samba share), making push into a local directory to fail. Thus, defer the chmod() call in index-pack.c:final() only after move_temp_to_file() was called.
