Currently the
http://sourceforge.net/p/smartmontools/code/HEAD/tree/trunk/smartmontools/drivedb.h?format=raw
and related files on sourceforge aren't available and therefor
cause our builds to fail with:
| Updating smartmontool drivedb
| /usr/sbin/update-smart-drivedb: download from trunk failed (HTTP error)
Therefore don't break our builds but instead log a warning
message instead.
