lib/krb5: verify_logonname() to handle multi component principal

FreeIPA can generate tickets with a client principal of
'host/hostname.example.com'.

verify_logonname() should just verify the principal name
in the PAC_LOGON_NAME is the same as the principal of
the client principal (without realm) of the ticket.

Samba commit b7cc8c1187ff967e44587cd0d09185330378f366
break this. We try to compare ['host']['hostname.example.com']
with ['host/hostname.example.com]' (as we interpret it as enterprise principal)
this fail if we don't compare them as strings.
