tpm_lite: Fix delegation table parsing

The computation to determine the number of table entries was incorrect
due to sizeof(TPM_FAMILY_TABLE_ENTRY) producing a wrong value for the
size of a single entry. TPM_FAMILY_TABLE_ENTRY actually doesn't match
the encoding of the entries in the TPM's response due to alignment.
Fix this by using a constant that reflects the correct entry size.

Relatedly, I found that ReadDelegationFamilyTableTest would have
caught the bug, but was actually not being invoked. Fix this as well.
