net-mgmt/nagios-check_smartmon: adjust it to work with more drives

[dvl]

Summary

The current release does not work with a wider range of drives. Case in point, it fails outright with this example.

[dan@r720-01:~] $ /usr/local/bin/sudo /usr/local/libexec/nagios/check_smartmon -d /dev/da2
Traceback (most recent call last):
  File "/usr/local/libexec/nagios/check_smartmon", line 318, in <module>
    (healthStatus, temperature) = parseOutput(healthStatusOutput, temperatureOutput, devtype)
  File "/usr/local/libexec/nagios/check_smartmon", line 219, in parseOutput
    temperature = int(parts[-3])
ValueError: invalid literal for int() with base 10: 'Temperature:'
[dan@r720-01:~] $

[dvl]

Without the patch:

[dan@r720-01:~] $ sudo /usr/local/libexec/nagios/check_smartmonon -d /dev/da2
Traceback (most recent call last):
  File "/usr/local/libexec/nagios/check_smartmon", line 318, in <module>

    temperature = int(parts[-3])
ValueError: invalid literal for int() with base 10: 'Temperature:'

With the patch:

[dan@r720-01:~] $ sudo ~/check_smartmon -d /dev/da2
OK: device (/dev/da2) is functional and stable (temperature: 0)|TEMP=0;55;60;

Given that reading a diff of a patch is difficult, the following is a diff of the installed code against my working code. This is copy/pasted so tabs etc may be wrong.

Fix the patch. I don't know why it was failing.

This is a help message. I'm fixing the text to match the code.
