Remove tcp wrapper configuration keywords that did not actually change anything.

The allow_severity and deny_severity variables are valid only for tcpd and
related applications, hosts_access does not use them.

* lib/tcpwrap.c (mu_tcp_wrapper_cb_hosts_allow_syslog)
(mu_tcp_wrapper_cb_hosts_deny_syslog): Remove functions.
(allow_severity, deny_severity): Remove variables.
(tcpwrapper_param): Remove allow-syslog-priority and
deny-syslog-priority.
