vc/eltan/security/verified_boot/vboot_check.c: Increase wb_buffer size
Running commit aee0baf0690681fae85d24e6887d6cbb9209de83 on
Facebook fbg1701 results in an error:
VB2:vb2_rsa_verify_digest() ERROR - vboot2 work buffer too small!
ERROR: HASH table verification failed!
The actual vboot structures require more space.
Workbuffer size needs to be increased.
We didn't determine the commit causing the issue because this change
fixes the issue.
BUG=N/A
TEST=Build and boot Facebook fbg1701
