vboot2: Allocate more buffer for kernel verification
The low-level verification functions' *_WORKBUF_BYTES constants assume
the work buffer is already aligned to VB2_WORKBUF_ALIGN. But malloc()
may return a less-aligned pointer, in which case vb2_workbuf_init()
aligns it (and loses a bit of space in the process). This can cause an
error "vb2_rsa_verify_digest: ERROR - vboot2 work buffer too small!".
High-level functions should be using the *_WORKBUF_RECOMMENDED_SIZE
constants for allocation, which have enough padding to compensate for
alignment problems.
