sysutils/munin-node: Lookup registered plugins case-insensitively

Conditions to reproduce
=======================

The hostname Munin discovers or is configured with (host_name) contains uppercase characters.


Expected behavior
=================

$ telnet localhost 4949
Trying ::1...
Connected to localhost.
Escape character is '^]'.
# munin node at HostName.example.COM
list
cpu if_igb0 if_packets_igb0 iostat load memory systat users
quit
Connection closed by foreign host.


Observed behavior
=================

$ telnet localhost 4949
Trying ::1...
Connected to localhost.
Escape character is '^]'.
# munin node at HostName.example.COM
list

quit
Connection closed by foreign host.


Workaround
==========

A) Set an all-lowercase host name in the munin-node config:

    host_name hostname.example.com

OR

B) Set an all-lowercase host name in the munin-master config, and don't snoop the connection banner:

    [Group;hostname.example.com]
    # ...
    use_node_name no


Fix
===

This has been fixed upstream but not yet released. The attached patch backports the fix.
