Fix compilerwarning in logging size_t

The pg_fatal log which included filesizes were using UINT64_FORMAT for
the size_t variables, which failed on 32 bit buildfarm animals. Change
to using plain int instead, which is in line with how digestControlFile
is doing it already.

Per buildfarm animals florican and lapwing.
