rename session cookie

With the default PHPSESSID cookie name, there are some rare (and hard to
debug) cases that break logging in if a different application on the
domain also uses a PHPSESSID cookie. See
https://sourceforge.net/p/postfixadmin/bugs/314/ for details.

Using 'postfixadmin_session' as cookie name should fix this.
