requires: use atomictemp=True when writing .hg/requires
We use an unusual file system at Google that allows writes (and
renames) but not deletions (for certain paths). That causes problems
when writing the requires files without atomictemp=True. There doesn't
appear to be any real drawbacks to using atomictemp, so I'm hoping we
can just change it in core.
