Because I was lazy and didn't think it through all that well :/

The problem with creating a value_string64 (or similar solutions) is that it
seems reasonable for a set of value_strings to be shared between a fields of
different sizes (uint8 through uint64) and doing that would require two copies
of the value_string: one for uint64 and one for all the others.
I did a quick check of the memory cost of just making all value-strings 64-bit
(basically s/32/64/ in value_string.[ch]): libwireshark.so grew by only about
60KB. I'm not sure if this would have a performance impact on 32-bit systems (I
don't have one handy to test) but if it's not too bad then this is probably the
simplest solution.
