Better validate key_data_ver in iprop decoding

In ulog_conv_2dbentry(), when decoding an update's AT_KEYDATA
attribute, the decoded key_data_ver value is used as a bound on the
enctype and contents fields.  Verify that this value does not exceed
the sizes of the update's enctype and contents XDR arrays, to prevent
reading past the end of those arrays.  Also check against the expected
lower bound.  Reported by Haruki Oyama.
