replace '3dinfo'

[GoogleCodeExporter]

unixbench tries to execute '3dinfo' command to get info about graphic system (I 
guess).
I found this program only in OpenSuse package 3ddiag and it looks that right 
now dumping expected info is commented out.
So, on most (all?) systems trying to run 3dinfo is pointless.
I think that 3dinfo should be replaced with something newer - maybe some part 
of 'glxinfo' output or 'hwinfo'.
