INT64_FORMAT in translatable strings

Hello.

I found the following lines in xlogprefetch.c.

> ereport(LOG,
> (errmsg("recovery finished prefetching at %X/%X; "
> "prefetch = " UINT64_FORMAT ", "
> "skip_hit = " UINT64_FORMAT ", "
...

It is found in ja.po as

"recovery finished prefetching at %X/%X; prefetch = "

. . . .

Anyway we can rely on %lld/%llu and we decided to use them in
translatable strings. So the attached fixes (AFAICS) all instances of
the macros in translatable strings.

# I just found 3286065651 did one instance of that so I excluded that
# from this patch.

regards.
