Brad King 221ffabfad TestDriver: Fix -Wconversion warning
Since commit v3.8.0-rc1~51^2~1 (TestDriver: calc NumTests at compile
time, 2017-01-24) we convert an expression that uses `sizeof()` to an
`int` as a compile-time constant.  Some GCC versions warn about this
with `-Wconversion`.  Add a cast to avoid the warning.
