GBB: set bmpfv_size to 0 when --skip-bmpblk

This patch sets bmpfv_size to zero when creating GBB with --skip-bmpblk
flag. Depthcharge checks bmpfv_size == 0 to decide whether vboot screens
should be drawn by VbExDisplayScreen or VbDisplayScreenLegacyFromGBB.

TEST=built chromeos-bootimage and exmained GBB header by hexdump. Booted
Jerry in normal, dev and recovery mode.
