[2.12+2.13] backport dovecot profile additions
This is a partial backport of bc36daa2 (without the abstractions/nameservice removal in usr.lib.dovecot.pop3-login)
Original commmit message:
dovecot: align {pop3,managesieve}-login to imap-login
Those 3 login daemons should have similiar needs and thus similar profiles. IMAP is likely the most tested one so let's align the other 2 with it. Unix and TCP sockets rules were added to pop3-login after the removal of abstractions/nameservice that included them implicitly.
