FIPS setup: fix typo filtering camellia encryption

The config file /var/kerberos/krb5kdc/kdc.conf is customized
during IPA server installation with a list of supported
encryption types.
In FIPS mode, camellia encryption is not supported and should
be filtered out. Because of a typo in the filtering method,
the camellia encryptions are appended while they should not.

Fix the typo (camelia vs camellia) in order to filter properly.
