intel/common: compress VBT
It's pretty well compressible which helps when space is tight. The code encodes the assumption that the VBT is 8kb or less. Haven't seen a larger one yet. BUG=b:77971803,b:78541692 TEST=build, see that vbt.bin is compressed, boot, check log that the reported VBT size is correct.
