test_custom_stats: Fix compilation warning

I have fat-fingered an error message related to an offset while
switching the code to use pgoff_t.  Let's switch to the same error
message used in the rest of the tree for similar failures with fseeko(),
instead.

Per buildfarm members running macos: longfin, sifaka and indri.
