Plugin hddtemp_smartctl has a bug in trunk

[boss-chifra]

Line 131 should return the version number of smartctl

if ($smartctl and `$smartctl --version` =~ / version (\d+\.\d+) /i)

in version 5.38 it is working properly

Redhat 5.x
smartctl --version

As we can see, the word "version" in the output isn't present more.
I suggest replace "version" to "release", because it is everywhere.
Then version of smartctl will be determined correctly for 5.3x and 5.4x
The line 131 should look like this.

if ($smartctl and `$smartctl --version` =~ / release (\d+\.\d+) /i)
