Fix verification of RODC-issued PAC KDC signature

Per [MS-PAC] 2.8, PAC_SIGNATURE_DATA may contain an RODCIdentifier
following the checksum.  In k5_pac_verify_kdc_checksum(), do not
assume that the checksum spans the remainder of the buffer; instead,
look up the checksum length by its type.

[ghudson at mit.edu: edited commit message and comment; reordered code
for clarity]
