The functions `header_size()` and `footer_size()` return a positive
integer representing the size of the header and footer, respectively,
dependent on the version of the reftable format. Similar to the
preceding commit, these functions return a signed integer though, which
is nonsensical given that there is no way for these functions to return
negative.
Adapt the functions to return a `size_t` instead to fix a couple of sign
comparison warnings.
