net-mgmt/monitoring-plugins: Update to 3.0.1

*) Security: fix a potential local privilege escalation in check_icmp,

which might be possible if check_icmp runs with setuid (the default)

*) Change: check_nt, check_ntp, check_nwstat and check_overcr were

removed upstream; check_ntp is replaced by check_ntp_time and
check_ntp_peer

*) Change: check_http is deprecated in favor of check_curl
*) Change: check_snmp now uses net-snmp natively instead of executing

snmpget

*) Change: generalized, mostly multi-line output for many plugins
*) Fix: check_curl now populates the DNS cache when the hostname is

resolved locally
