The google authenticator PAM module will write the `.google_authenticator` 
files with permission `400 (-r--------)` and then Allura can't write to it.  We 
also need to write it with `400` or `600` perms, so it is secure for PAM to use 
it afterwards.  And best to do it atomically, with a file rename operation.
