login_yubikey does not accept user.name

[Björn Ketelaars]

login_yubikey does not accept user names with a dot (e.g. user.name).
If one is offered login fails. As other authentication types (e.g.
login_passwd) do accept the use of a dot, it seems that this is a
'feature' related to login_yubikey.

A small patch:

ok?
