vc/eltan/security/verified_boot/vboot_check.c: Increase wb_buffer size 

Running commit aee0baf069 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
