utils: user schema: explicitly forbid @ in user-names

Browse Source 
PMGs terms are:
* 'userid' consists of 'username'@'realm'

without this patch it was possible to create a user through the api,
with @ in the username ('foo@bar@pmg'), and it got written to the
user-conf.
Reading that entry was not possible, as the verification on read was
stricter.

This patch forbids '@' in usernames, and additionally drops the
maxLength of 64, as 60 are already enforced by the regex pattern match
(leaving 4 as minimal length for '@pmg'/'@pam').

Potential for regression should be minimal (the users could not be
read-back from the config).
