[Beignet] [PATCH V2] gbe_bin_generater: fix two bugs.

[Yang, Rong R]

How about retry if get empty pci id.

For example:
lspci -nn | grep " VGA.*Gen .* Graphics" -i  | grep "\[8086:.*\]" -o | awk -F : '{print $2}' | awk -F ] '{print $1}'
if [ -z "$1" ]; then 
  lspci -nn | grep " VGA.*Intel .* Graphics" -i  | grep "\[8086:.*\]" -o | awk -F : '{print $2}' | awk -F ] '{print $1}'
fi
if [ -z "$1" ]; then 
  lspci -nn | grep " VGA.* Graphics.*8086" -i  | grep "\[8086:.*\]" -o | awk -F : '{print $2}' | awk -F ] '{print $1}'
fi

Some PCI ID do not have Gen keyword, such as ruiling's  IVBridge XXXXXX So need to refine the command line
