[sql] Lower SQLITE_PRINTF_PRECISION_LIMIT for fuzzer.

Real-world usage should never involve precisions above maybe 100.  The
previous limit of 128M makes it very easy to blow out memory when
fuzzing, and since OOM is already fatal, I'm not sure that such a
large limit provides any productive coverage beyond something more
reasonable.
