dovecot: Match also when user field is empty
Commit 5678d08
of 2016-11-26 changed:
( user=<\S*>,)?
to:
( user=<[^>]+>,)?
The change from `*` (zero or more times) to `+` (one or more times) may
not have been intended. It will miss lines containing, for example:
Aborted login (tried to use disallowed plaintext auth): user=<>
This commit reverts the `+` back to `*`.
