[Dovecot] 1.1.20 patch - PAM file cleaup

Hi,

This patch prevents a temp file cleanup issue related to PAM. It
appears to be relevant only to 1.1 dovecot code. It seems pretty
sensible. From what I can tell, it's not included in the 1.1.20
release. I'm not clear if it was ever reported. Could it be merged in
for future releases?

Thanks, Todd Rinaldo
