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.
