Windows: fix utime() for read-only files
Starting with 5256b00 (Use git_mkstemp_mode instead of plain mkstemp to
create object files, 2010-02-22) utime() is invoked on read-only files.
This is not allowed on Windows and results in many warnings of the form
failed utime() on .git/objects/23/tmp_obj_VlgHlc: Permission denied
during a repack. Fix it by making the file temporarily writable.
