bug#12632: file permissions checking mishandled when setuid

In addition, I don't understand why is it a good idea to use
'euidaccess' in check_existing.  Isn't the fact of the mere existence
of a file independent of user's access rights?

If 'access' is as good here as 'euidaccess', I think we should use the
former, as it is less expensive than the latter (AFAIU).
