journal: prevent integer overflow while validating header (#5569)
It is possible to overflow uint64_t while validating the header of
a journal file. To prevent this, the addition itself is checked to
be within the limits of UINT64_MAX first.
To keep this readable, I have introduced two stack variables which
hold the converted values during validation.
