branches/zip: rec_convert_dtuple_to_rec_comp(): Allow externally stored

Browse source 
columns to be up to REC_MAX_INDEX_COL_LEN + BTR_EXTERN_FIELD_REF_SIZE
bytes in a debug assertion.  This assertion could fail since r2159 in
trx_undo_prev_version_build(), because the undo log records for updates
and deletes would contain longer prefixes of externally stored columns.

The assertion failure was reported by Sunny.
